Products Active Components Silicon avalanche photodiodes flatness, and a low 0.02% total harmonic distortion yield excellent audio signal quality. The MAX4908/MAX4909 use two digital control inputs—CB1 and CB2—to switch between signals. The digital control inputs can accept up to +5.5 V independent of the supply voltage. The switches are available in the extended temperature range of -40 °C to +85 °C and in a tiny 12-bump UCSP (1.5 mm x 2.0 mm) and a 14-pin TDFN package (3 mm x 3 mm). Prices start at $1.20, in 1000 pieces and up. Maxim Integrated Products (408) 737-7600 www.maxim-ic.com Ultraminiature linearized VVA The SAR500x Si-APD from Laser Components has a 500 m detector chip with a “reach through” structure. This structure is responsible for a high sensitivity in the spectral range of 400 nm to 1100 nm and simultaneously for extremely fast rise and fall times, typically of 450 ps. The SAR500X is delivered in a hermetically sealed TO-18 can. The SAR500X is designed for a wide range of uses, including laser range finding and optical communication with data transfer rates of up to 1 Gbps. Such uses make sense where high speed and/or a high sensitivity are necessary. The SARP500x is an SAR500S-type APD that has been selected for low noise and low dark currents (typically 200 pA@M = 100). It is, therefore, suitable for the detection of the smallest amount of light. The SARP500 series can be delivered in a TO-18 can or with a thermoelectric cooler in a TO-37 can. This APD is additionally suitable for use in spectroscopy, fluorescence measurement, medical technology, and LIDAR applications. Laser Components (603) 821-7040 www.laser-components.com SP3T analog switches Maxim Integrated Products’ MAX4908/ MAX4909 are dual, single-pole triple-throw (SP3T) analog switches designed to handle negative signals with a single positive power supply. This reduces external component count and improves audio signal quality. The negative-signal capability allows signals as low as VCC -5.5 V to pass through without distortion. They operate from a single +1.8 V to +5.5 V supply. Other features include integrated shunt resistors to ground, thereby reducing audio popping and clicking sounds by depleting the capacitive charge, which commonly builds up on the unconnected port of the switch to ground. In addition, an extremely low 0.38 on-resistance, a low 0.35 on-resistance 60 RH Laboratories has introduced a solidstate voltage variable attenuator (VVA) that provides 50 dB of dynamic range (0 V to 5 V) over a broad bandwidth of 10 GHz to 18 GHz in an ultraminiature package (0.75 in. x 0.53 in.). Linearization and temperature compensation are included with flat frequency response. The convenient single dc voltage supplied is +15 V. GPO and SMA removable connector options are available, allowing for drop-in applications. RH Laboratories (603) 459-5900 www.rh-labs.com Amplifiers HSDPA-compliant WCDMA amps Anadigics has introduced its third-generation high-efficiency-at-low-power (HELP3) wideband CDMA (WCDMA) power amplifiers (PAs). The company’s HELP3 WCDMA PAs offer low power consumption and provide full compliance with high downlink packet access (HSDPA) requirements, enabling ultrafast multimedia access while extending battery life. The complete family of HELP3 WCDMA PAs has been optimized for power and space-sensitive 3G devices, including handsets, smart phones, data cards, and embedded notebook applications. The PAs use the company’s InGaP-Plus technology, which integrates bipolar and www.rfdesign.com field-effect transistor (FET) devices on the same InGaP GaAs die. Through selectable bias modes, the HELP3 PAs achieve optimal efficiency across the low-range and mid-range output power levels. The PAs reduce average current consumption by 75%, compared to a conventional power amplifier. This represents an additional 50% average current consumption savings compared with the first-generation HELP WCDMA PAs. HELP3 PAs provide low quiescent currents of 7 mA without an external dc-dc converter. They also incorporate a built-in reference voltage generator, eliminating the need for external regulators. The power amplifiers are offered in compact 4 mm x 4 mm x 1 mm modules. The products are manufactured using a materials set consistent with the European Union’s Restriction of Hazardous Substances (RoHS). The AWT6273, AWT6278, AWT6279 are priced at $2.58 in quantities of 10,000 units.

Atmel (408) 441-0311 www.atmel.com Medical Electronics Biopatch medical monitoring Agilent Technologies Inc. has announced a breakthrough in its core electronic design automation (EDA) frequency-domain simulation technology for fast and accurate simulation of highly non-linear circuits, such as digital dividers used in RFIC circuits. This simulation breakthrough provides crucial circuit performance information that can help avoid design errors leading to an extra design turn. Digital divider circuits are examples of highly non-linear circuits used as part of larger, mixed-signal and RF circuits, such as transceivers for cell phones, for wireless communication devices such as WiFi, WiMAX and UWB, and for frequency generation of LO drives for frequency translation circuits or I/Q modulator/demodulators. In the past, these highly non-linear digital dividers and their attendant simulation problems often prevented a complete chip simulation in mixedsignal and RF circuits. Now, these complex chip circuits simulate and converge quickly— shortening design cycles and, in many cases, eliminating an entire design turn. The enhanced simulator in ADS and RFDE is available free to supported ADS and RFDE customers. For new customers, it is available for purchase with ADS 2005A and RFDE. Agilent ADS 2005A is available, with prices starting at approximately $8400. Yearly subscription prices for RFDE start at approximately $24,000.

Zarlink Semiconductor (613) 592-0200 www.zarlink.com Zero delay buffers Exar Corporation has added a family of low-skew and low-jitter zero delay buffers (ZDB) to Exar’s portfolio of clock and timing solutions. Operating at higher speeds than Exar’s initial ZDB solutions, the XRK39351 and XRK39653 give designers additional options for current and nextgeneration architectures. Operating at speeds of up to 200 MHz, each device distributes one clock input to a bank of nine outputs, that reults in low-skew, low-jitter copies of each clock. The devices accurately align the feedback output to the clock input signal ensuring a zero delay through the IC. The devices offer tight cycleto-cycle jitter spec at less than 22 ps rms to ensure the production of stable and clean signals. In addition, the XRK39351 operates at either 3.3 V or 2.5 V, and the XRK39653 operates at only 3.3 V. The XRK39351 and XRK39653 have a fan-out phase locked-loop clock driver intended for high-performance computing, telecommunications and data-communications applications. The internal loop filter is tuned to minimize the jitter (or frequency variation) while still providing accurate responses to input frequency changes. The XRK39351 offers nine zero delay outputs with less than 150 ps of output-to-output skew, LVCMOS/LVPECL reference inputs, and an output frequency of 25 MHz to 200 MHz. The XRK39653 also offers eight zero delay outputs (along with one dedicated feedback) with less than 150 ps of output-output skew, and an output frequency of 25 MHz to 125 MHz.
