HMC356LP3 / 356LP3E v02.0605 AMPLIFIERS - SMT 5 GaAs PHEMT MMIC LOW NOISE AMPLIFIER, 350 - 550 MHz Typical Applications Features The HMC356LP3 / HMC356LP3E is ideal for basestation receivers: Noise Figure: ≤1.0 dB • GSM 450 & GSM 480 Gain: 17 dB • CDMA 450 Very Stable Gain vs. Supply & Temperature • Private Land Mobile Radio Single Supply: +5.0V @ 104 mA +38 dBm Output IP3 50 Ohm Matched Output Functional Diagram General Description The HMC356LP3 & HMC356LP3E are high dynamic range GaAs PHEMT MMIC Low Noise Amplifiers is ideal for GSM & CDMA cellular basestation and Mobile Radio front-end receivers operating between 350 and 550 MHz. This LNA has been optimized to provide 1.0 dB noise figure, 17 dB gain and +38 dBm output IP3 from a single supply of +5.0V @ 104 mA. Input and output return losses are 15 dB typical, with the LNA requiring only four external components to optimize the RF input match, RF ground and DC bias. The HMC356LP3 & HMC356LP3E share the same package and pinout with the HMC372LP3 high IP3 LNA. A low cost, leadless 3x3 mm (LP3) SMT QFN package houses the low noise amplifier.
