TriQuint’s AP561 and AP562 amplifiers deliver greater than 1 W linear power at 2.5 percent EVM, offering 13 percent PAE to meet the needs of ultra-efficient systems. The AP561 offers 12 dB gain across the 2.3 to 2.9 GHz band; the AP562 offers 12 dB gain across the 3.3 to 3.8 GHz band. The high output linear power and efficiency of these devices make them ideal for outdoor customer premise equipment (CPE) applications in WiMAX systems.

TriQuint’s AH314 and AH315 amplifiers provide very low EVM (error vector magnitude) under high back-off power operating conditions while also offering very good gain flatness: less that 0.2 dB over 100 MHz. The AH314 is a two-stage amplifier with 23 dB gain operating from 2.3 to 2.9 GHz; the AM315 offers 25 dB gain from 3.3 to 3.8 GHz. The AH314/315 are ideal for WiMAX base transceiver station (BTS) applications requiring linearity margin prior to final stage amplifiers within the system.
