GPRS power amplifier module meets Class 12 profile
The ECM007, from EiC, is a fully matched dual-band GSM/DCS1800 power amplifier module that meets or exceeds the demanding GPRS Class 12 operating profile. This power amplifier module is designed using EiC's proprietary InGaP HBT process and, together with a low thermal resistance IC design, allows for GRPS Class 12 performance that requires up to a 50% duty cycle operation. The ECM007 provides a minimum output power of 34.5 dBm in Class IV GSM operation and provides band select and analog power control features.

Power amplifier RFICs deliver linearity for cellular/PCS/3G
Stanford Microdevices introduces its SPA Series of power amplifier radio-frequency integrated circuits (RFICs). These products offer cellular, PCS and 3G equipment designers a level of linearity performance formerly unavailable in a single integrated circuit. The amplifiers are intended for the most demanding wireless network system requirements. These devices cover the 850 MHz, 1950 MHz and 2150 MHz frequency bands and serve as driver amplifiers for base station and repeater applications. Housed in standard surface-mount SOIC8 plastic packages with backside metallization, the amplifiers provide the exceptional linearity demanded by advanced network modulation standards.
FM/FSK transmitter IC operates in 26 MHz band
The NT2800 is a complete, fully integrated, single-chip, FM/FSK transmitter IC that will operate in any 26 MHz band from 800 — 1000 MHz, on a 2.7 to 3.3 VDC supply. The device integrates on an on-chip VCO, phase-locked loop, and reference oscillator. The NT2800 accepts either analog or data as input to the modulator (direct modulation). Tuning is accomplished via a three-wire serial interface. Power output is +1.5 dBm. Packaging is a 16-pin QSOP.
ATE systems for wireless RFIC provide new test choices
Credence System's RFx is a mixed-signal test system for cost-sensitive, high-volume production testing of RF/wireless devices for low cost-of-ownership. This full mixed signal system design provides test engineers new technology test choices for comprehensive RF device testing. The RFx is designed specifically for testing devices used in wireless, cellular, and personal communications.

240 W high-power GaAs FET for L-band applications
A new high-power GaAs FET with an output of 240 W for use in the 2.1 to 2.2 GHz frequency range is available from Fujitsu Compound Semiconductor. The FLL2400IU-2C employs a push-pull design that offers ease of matching, greater consistency, and a broader bandwidth for high-power amplifiers. This product is used for solid-state, base-station, power amplifiers for W-CDMA and IMT 2000 communications systems applications. The device uses an enhanced GaAs power field-effect transistor process that uses a gold gate (Au) metallization process with increased gain and improved third-order IM performance.

Power meter for accurate CW measurement
Krytar's new RF/microwave power meter was developed specifically for engineers needing to accurately measure CW or swept RF and microwave power in the field or in the lab. Auto-ranging linearity is ±0.05 db. Accurate CW power measurement range is -30 to +20 dBm (useable to -39 dBm). The unit provides a DC output voltage of -3.9 to +2.0 volts, which is equivalent to power input of -39 to +20 dBm (allows low-cost swept scalar measurements). Optional RS232 serial port or IEEE-488 interface bus is available.

MC-card connectors for use in cellular devices
RF Connectors has added two new special application connectors to its line of subminiature coaxial connectors. Designed for use in cellular devices where board and chassis space is limited, these right-angle connectors mate with PCB and card-mounted jacks. The RMC-610-A connector is available for RG-178/U and the RMC-6010-B is designed for use with RG-174/U, RG-188/U and RG-316/U cables. Bodies are of nickel-plated, machined brass, and contacts are gold-plated BeCu. The insulation is teflon.
