General Description

The HMC688LP4(E) is a high dynamic range passive

MMIC mixer with integrated LO amplifier in a 4x4 SMT

QFN package covering 2.0 to 2.7 GHz. Excellent input

IP3 performance of +35 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 7.5 dB typical.

The DC to 700 MHz IF frequency response will satisfy

GSM/CDMA transmit or receive frequency plans.

The HMC688LP4(E) is pin for pin compatible with the

HMC689LP4(E) which is a 2.0 - 2.7 GHz mixer with

LO amplifier optimized for high side LO applications.
