General Description
The HMC785LP4E is a high dynamic range passive
MMIC mixer with integrated LO amplifier in a 4x4
SMT QFN package covering 1.7 to 2.2 GHz. Excellent
input IP3 performance of +38 dBm for down conver-
sion is provided for 3G & 4G GSM/CDMA applications
at an LO drive of 0 dBm. With an input 1 dB com-
pression of +26 dBm, the RF port will accept a wide
range of input signal levels. Conversion loss is 8 dB
typical. Up to 300 MHz IF frequency response will
satisfy GSM/CDMA transmit or receive frequency
plans. The HMC785LP4E is optimized for low side
LO frequency plans for 1.7 - 2.2 GHz RF Band and is
pin for pin compatible with the HMC685LP4E
