| v01.0604 MICROWAVE CORPORATION HMC373LP3 Features Noise Figure: 0.9 dB +35 dBm Output IP3 Gain: 14 dB Low Loss LNA Bypass Path Single Supply: +5.0 V @ 90 mA 50 Ohm Matched Output GaAs PHEMT MMIC LOW NOISE AMPLIFIER w/ BYPASS MODE, 700 - 1000 MHz 8 AMPLIFIERS - SMT Typical Applications The HMC373LP3 is ideal for basestation receivers: * GSM, GPRS & EDGE * CDMA & W-CDMA * Private Land Mobile Radio Functional Diagram General Description The HMC373LP3 is a versatile, high dynamic range GaAs MMIC Low Noise Amplifier that integrates a low loss LNA bypass mode on the IC. The amplifier is ideal for GSM & CDMA cellular basestation frontend receivers operating between 700 and 1000 MHz and provides 0.9 dB noise figure, 14 dB of gain and +35 dBm IP3 from a single supply of +5.0V @ 90 mA. Input and output return losses are 28 and 12 dB respectively with the LNA requiring minimal external components to optimize the RF input match, RF ground and DC bias. By presenting an open or short circuit to a single control line, the LNA can be switched into a low 2.0 dB loss bypass mode reducing the current consumption to 10 A. A low cost, leadless 3x3 mm QFN surface mount package (LP3) houses the low noise amplifier. Electrical Specifications, TA = +25 C, Vdd = +5V LNA Mode Parameter Min.
