Cacade also featured Pureline wafer probing systems that allow semiconductor manufacturers to model, characterize and test the latest generation of integrated circuits required for today’s demanding applications. With its seventh-generation high voltage (HV7) RF LDMOS technology, Freescale Semiconductor has achieved the RF power transistor performance required for use in WiMAX base stations operating in the 3.5 GHz band. Freescale claims this achievement marks the first time RF laterally diffused metal oxide semiconductor technology from any manufacturer has met these challenges. Keithley Instruments Inc. introduced its new model 2910 RF vector signal generator that offers capabilities and ranges making it ideal for production testing of today's sophisticated mobile handsets as well as for applications such as communications research, the testing of mobile communications infrastructure, RFICs and wireless connectivity devices. The model 2910's continuous frequency range of 400 MHz to 2.5 GHz spans key mobile wireless bands. Lark Engineering Co. featured its family of surface-mount combline filters from 5 to 15 GHz, with a bandwidth from 3 to 20 percent and exceptionally low insertion loss. M/A-COM was displaying model MAAPSS0076, a RoHS-compliant, DECT power amplifier for applications that require dual power modes, high gain and small size at a low cost. Also on display was model MAATSS0022, a RoHS-compliant 5-bit serial controlled attenuator for applications that require high accuracy and monotonic performance at a low cost. The model TU-3840 wideband ELINT tuner is designed for use in high end signal processing military applications and is based on the company’s successful, SEI-certified, SMR-3822 RF microwave sweeping receiver technology. Model MA4PBL027 HMIC silicon beam lead PIN diode is the most recent addition to the beam lead PIN diode group.

Peregrine Semiconductor featured its 75 ohm UltraCMOS™ switches that provide good isolation, linearity and ESD tolerance for today’s most demanding CATV and DTV applications. Also on display were UltraCMOS phase-locked loops, prescalers and mixers that are manufactured on the company’s proprietary UltraCMOS™ silicon-on-sapphire process technology. These products draw from many years of high performance RF CMOS and mixed-signal IC experience. Wireless UltraCMOS™ switches feature high isolation, high ESD tolerance and low insertion loss, providing an optimal solution for most any wireless application.
Radio Waves Inc. announced a breakthrough in microwave antenna technology with a new generator of the company's HP3-11 3' high performance dish. The new HP3-11 provides FCC Cat A performance for the 11 GHz band in a three-foot dish. Previously network designers and operators were required to utilize a four-foot dish for links to be considered Cat A complaint. By utilizing a three-foot dish, network planners can easily pass local zoning rules in regards to antenna size on building structures.
RF Micro Devices Inc. announced the commercial launch of its complete POLARIS 2™ TOTAL RADIO™ Module solution, which is comprised of a cellular transceiver module and a cellular transmit module for handsets operating on the GSM/GPRS and GSM/GPRS/EDGE networks.
