MRFIC1819 3.6 V 18OO MHz GaAs Integrated Power Amplifier
The MRFIC1819 is a single supply, RF power amplifier designed for the 1W DCS1800/PCS1900 handheld radio. The negative power supply is generated inside the chip using RF rectification, which avoids any spurious signal. A built in priority switch is provided to prevent Drain Voltage being applied on the RF lineup if not properly biased by the Negative Voltage. The device is packaged in the TSSOP–16EP package, with exposed backside pad, which allows excellent electrical and thermal performance through a solderable contact. Target 3.6 V Characteristics: RF Input Power: 6.0 dBm RF Output Power: 33 dBm Typical Efficiency: 41% Typical Single Positive Supply Solution
