All of which combine to provide for best in class harmonic emission control and RX and TX insertion loss.
The device is self-contained with 50 Ω input and output terminals with no matching components required.
The integrated power control function based on RFMD’s patented Power Star© control is incorporated, eliminating the need for directional couplers, Functional Block Diagram detector diodes, power control ASIC’s, and other power control circuitry; this allows the module to be driven directly from the DAC output.
The device is designed for use as the final portion of the transmit chain in GSM850, EGSM900, DCS and PCS GMSK and eliminates the need for PA to antenna switch module matching.
On-board power control provides over 70dB control range.
The integrated antenna switch allows true quad band TX and RX functionality.
Built-in current limiter option may be utilized to minimize power variation in mismatch condition.
