  • PERFORMANCE (3.5 GHz) (802.16-2004 WiMAX Modulation) ♦ 30 dBm Typical Output Power, < 2.5% EVM ♦ 14 dB Typical Small-Signal Gain ♦ Class B Efficiency 14% (8V / 720 mA IDQ) ♦ > 48 dBm 3rd Order Intercept Point ♦ Low total components count
  • DESCRIPTION AND APPLICATIONS The FRD3500X230 is a 2-stage, connectorized Reference Design that delivers a typical linear power of 30 dBm with the 802.16-2004 modul ation, while maintaining less than 2.5% EVM. The design features a FPD4000AS driver stag e, 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.

  • Operating conditions that exceed the Absolute Maximum Ratings could result in permanent damage to the devices.
  • HANDLING PRECAUTIONS To avoid damage to the devices care should be exercised duri ng handling. Proper Electrostatic Discharge (ESD) precautions should be observed at al l stages of storage, handling, assembly, and testing. This product has be tested to Cla ss 1A (> 250V but < 500V) using JESD22 A114, Human Body Model, and to Class A, (< 200V) using JESD22 A115, Machine Model..
  • APPLICATIONS NOTES & DESIGN DATA Recommendations on matching circuits is available from your local Filtronic Sales Representative or directly from the factory. User must ensure that proper bias se quencing is observed: Gate bias must be applied before Drain bias, and during power-down the Drain bi as must be removed first.
