PRODUCT DESCRIPTION
The ANADIGICS AWM6431 WiMAX Power Amplifier
is a high performance device that delivers
exceptional linearity and efficiency at high levels of
output power. Designed to operate in the upper
portion of the 3.5 GHz band, it supports the IEEE
802.16-2004 and ETSI EN301-021 wireless
standards.
The device requires only a single +5 V to +6 V supply
and a low-current reference input. An integrated
detector can be used to monitor output power, and
an integrated 20 dB step attenuator enables gain
control. No external circuits are required for biasing
or RF impedance matching, thus reducing external
component costs and facilitating circuit board
designs.
The AWM6431 is manufactured using advanced
InGaP HBT technology that offers state-of-the-art
reliability, temperature stability and ruggedness. It
is optimized for use in a 50 Ω system, and is offered
in a 4.5 mm x 4.5 mm x 1.4 mm surface mount
module.

ELECTRICAL CHARACTERISTICS
T able 2: Absolute Minimum and Maximum Ratings
Stresses in excess of the absolute ratings may cause permanent damage. Functional operation is not
implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely
affect reliability.
T able 3: Operating Ranges
The device may be operated safely over these conditions; however, parametric performance is guaranteed
only over the conditions defined in the electrical specifications.
