WJ Introduces New Line Of Highly Linear 12 V Power Amplifier Modules
Targeted for 2.5 and 3G cellular base station applications
San Jose, CA -- WJ Communications, Inc. today introduced a new family of 12 V power amplifiers, the AP501, AP502, AP503, and AP504. The AP series is 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, VP of PAS and high voltage HBT program for WJ. "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."
The AP series high dynamic range power amplifier modules are 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 APs have the added feature of a 5 V power down control pin. A low-cost 29 mm by 13 mm by 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.
