( DataSheet : www.DataSheet4U.com ) Order this document by MRFIC1819/D 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 INTEGRATED RF POWER AMPLIFIER DCS1800/PCS1900 SEMICONDUCTOR TECHNICAL DATA 16 1 Negative Voltage Generator Positive Step–Up Voltage Generator VSS Check Switch for Gate–Drain Priority PLASTIC PACKAGE CASE 948L (TSSOP–16EP, Tape and Reel Only) PIN CONNECTIONS VP VD3 1 2 3 4 5 6 7 8 (Top View) 16 15 14 13 12 11 10 9 VDB VD0 InBuf RFin VD1 VD2 VSC VSS Simplified Block Diagram RFout RFout VD1 VD2 VD3 RFout Bias3 RF In RF Out Bias2 Bias1 Bias2 Bias3 VSS VP VSC Bias1 In Buf Negative Voltage Generator ORDERING INFORMATION VD0 VDB Device This device contains 9 active transistors.
