HMC684LP4 / 684LP4E v01.0408 MIXERS - DOWNCONVERTERS - SMT 8 BiCMOS MMIC MIXER W/ INTEGRATED LO AMPLIFIER, 700 - 1000 MHz Typical Applications Features The HMC684LP4(E) is Ideal for: High Input IP3: +32 dBm • Cellular/3G & LTE/WiMAX/4G Low Conversion Loss: 7 dB • Basestations & Repeaters Low LO Drive: 0 dBm • GSM, CDMA & OFDM Upconversion & Downconversion Applications • Transmitters and Receivers 24 Lead 4x4mm SMT Package: 16mm2 Functional Diagram General Description The HMC684LP4(E) is a high dynamic range passive MMIC mixer with integrated LO amplifier in a 4x4 SMT QFN package covering 0.7 to 1.0 GHz. Excellent input IP3 performance of +32 dBm for down conversion is provided for 3G & 4G GSM/CDMA applications at an LO drive of 0 dBm. With an input 1 dB compression of +25 dBm, the RF port will accept a wide range of input signal levels. Conversion loss is 7 dB typical. The DC to 450 MHz IF frequency response will satisfy GSM/CDMA transmit or receive frequency plans. The HMC684LP4(E) is pin for pin compatible with the HMC685LP4(E) which is a 1.7 - 2.2 GHz mixer with LO amplifier.
