DESCRIPTION AND APPLICATIONS
DEMO BOARD SIZE: 1 x 2 in. (2.54 x 5.08 cm.)
CONNECTORIZED VERSION SHOWN
The FRD3500X230 is a 2-stage, connectorized Reference Design that delivers a typical linear power
of 30 dBm with the 802.16-2004 modulation, while maintaining less than 2.5% EVM. The design
features a FPD4000AS driver stage, followed by a FPD10000AF power output stage. Both stages
are dual-biased to allow a range of bias conditions on each stage, allowing operation from Class B to
Class A. Board layout and components list are included.
