A new power amplifier from ANADIGICS has been released by Richardson RFPD with full design services support. The AWL5911 is an easy-to-use module that delivers high levels of linearity and efficiency for high data rate applications. Designed for the 5 GHz WLAN standards, it supports IEEE 802.11a/n/ac applications.

Requiring only a single +3V to +5V supply and a CMOS-compatible 1.8V enable voltage, the AWL5911 reduces system power consumption by offering a low leakage current while the amplifier is shut down.

The detector facilitates accurate power control (+/- 0.5 dB) over varying load conditions (3:1 VSWR).

No external circuits are required for RF impedance matching, which reduces component costs and makes it easy to incorporate the device into new designs. 

The AWL5911 is manufactured using an advanced InGaP HBT technology that offers state-of-the-art reliability, temperature stability and ruggedness.

It is offered in a 4 mm x 4 mm x 0.80 mm surface mount package optimised for a 50Ω system, and it is ideally suited for access points, media gateways, set-top boxes, and smart TV applications.

According to ANADIGICS, additional key features of the AWL5911 include:

  • 1.8% dynamic EVM @ POUT = +22 dBm with 802.11ac MCS9-HT80 waveform, 5V
  • 33 dB of linear power gain @ 5V
  • Power detector with high accuracy over 3:1 VSWR
  • 50Ω-internally matched RF ports
