US : WJ Communications introduced a new family of +12 V power amplifiers, the AP501, AP502, AP503 and AP504. The AP series are targeted for use as a driver or final stage amplifier in wireless infrastructure where high linearity and high power are required. This combination makes the device an excellent candidate for next generation multi-carrier 2.5/3G, PCS, UMTS and CDMA2000 base stations.

"The AP5xx family of PA modules provides cost-effective, high performance, high efficiency solutions for next-generation cellular base stations," said Barry Lin, vice president of PAS and high voltage HBT program for WJ Communications. "These modules reflect our breakthrough product design and semiconductor process capabilities. The AP5xx series integrates InGaP/GaAs HBT technology to provide our customers with better performance and greater value. This family of products is consistent with WJ's strategy to aggressively expand its addressable market size by entering the power amplifier segment of the cellular base station market."

Product Overview

The AP series are high dynamic range power amplifier modules optimized for driver or final stage amplifier mobile infrastructure. These devices are multi-stage, and are internally optimized for efficiency and linearity. Each PA module in the family features 50 ohm operation including internal matching for input and output and operates off +12 V without requiring negative biasing voltages. Additionally, an internal active bias allows the devices to maintain high linearity over temperature. The AP's have the added feature of a +5 V power down control pin. A low-cost 29 x 13 x 4 mm metal housing with bolt-down flange allows these devices to have a low thermal resistance and achieves over 100 years MTTF. All devices are 100% RF and DC tested. These devices were developed using the InGaP HBT process.
