FRD3500X230 Datasheet | Filtronic Compound Semiconductors

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 d Bm 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 ponents list are included. - ELECTRICAL SPECIFICATIONS AT 22°C Parameter Operating Bandwidth Small Signal Gain Gain Flatness Center Frequency (adjustable) Power at 1d B Gain pression Class A - CW Single Tone Power Gain at d B Gain pression Class A - CW Single Tone Channel Power with 802.16-2004 2.5% max.
