WiFi power amp delivers +22-dBm output

February 01, 2016 // By Susan Nordyk
Optimised for 802.11a/n/ac WiFi infrastructure, the Anadigics AWL5911 5-GHz power amplifier provides 33 dB of linear power gain and low 1.8% EVM (error vector magnitude) with a 5-V supply and output power of +22 dBm. An integrated power detector permits accurate ±0.5-dB power control over varying load conditions (3:1 VSWR).

The AWL5911 is manufactured using InGaP HBT (heterojunction bipolar transistor) process technology for enhanced stability and ruggedness. It requires only a single 3-V to 5-V supply and a CMOS-compatible 1.8-V enable voltage. This internal enable interface eliminates the need for an external buffer amplifier. The part also reduces power consumption by offering low leakage current when the amplifier is shut down.

With 50-Ω internally matched RF ports, the AWL5911 comes in a 4 × 4 × 0.80-mm surface-mount package. The device’s high level of integration reduces component cost and saves board space for use in such applications as access points, media gateways, set-top boxes, and smart TVs.

The Anadigics AWL5911 is available from Richardson RFPD and costs $1.13 (2500). An evaluation board for the AWL5911 is also available.
