HMC372LP3 / 372LP3E v02.0605 AMPLIFIERS - SMT 5 GaAs PHEMT MMIC LOW NOISE AMPLIFIER, 700 - 1000 MHz Typical Applications Features The HMC372LP3 / HMC372LP3E is ideal for basestation receivers: Noise Figure: <1.0 dB • GSM, GPRS & EDGE Gain: 15 dB • CDMA & W-CDMA Very Stable Gain vs. Supply & Temperature • Private Land Mobile Radio Single Supply: +5.0 V @ 100 mA +34 dBm Output IP3 50 Ohm Matched Output Functional Diagram General Description The HMC372LP3 & HMC372LP3E are GaAs PHEMT MMIC Low Noise Amplifiers that are ideal for GSM & CDMA cellular basestation front-end receivers operating between 700 and 1000 MHz. The amplifier has been optimized to provide 1.0 dB noise figure, 15 dB gain and +34 dBm output IP3 from a single supply of +5.0V @ 100 mA. Input and output return losses are 25 and 14 dB respectively with the LNA requiring only four external components to optimize the RF Input match, RF ground and DC bias. The HMC372LP3 & HMC372LP3E share the same package and pinout with the HMC356LP3 high IP3 LNA. A low cost, leadless 3x3 mm (LP3) SMT QFN package houses the low noise amplifier.
