This device works optimally at a drain bias of +9 V and 450 mA to achieve +46 dBm output IP3 performance and an output power of +34 dBm at 1-dB compression. The device conforms to WJ Communications’ long history of producing high reliability and quality components. The FP31QF has an associated MTTF of a minimum of 100 years at a mounting temperature of 85 °C. All devices are 100% RF & DC tested. The product is targeted for use as driver amplifiers for wireless infrastructure where high performance and high efficiency are required.

Pinch-off voltage is measured when Ids = 4.8 mA. 2. Test conditions unless otherwise noted: T = 25 ºC, VDS = 9 V, IDQ = 450 mA, in a tuned application circuit with ZL = ZLOPT, ZS = ZSOPT (optimized for output power). 3. 3OIP measured with two tones at an output power of +18 dBm/tone separated by 1 MHz. The suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.

Power @ -45 dBc ACLR dBm +25 Drain Voltage (5) V +9 Drain Current (5) mA 450 4. Typical parameters represent performance in an application circuit. 5. Empirical measurements showed optimal power performance at a drain voltage = 9 volts at 450 mA. Because the FP31QF is a discrete device, users can choose their own bias configuration. Performance may vary from the data shown depending on the biasing conditions. To achieve a minimum 1 million hours MTTF rating, the biasing condition should maintain a junction temperature below 160 °C over all operating temperatures. This can be approximated by (drain voltage) x (drain current) x 17.5 °C/W + (maximum operating temperature).
