Functional Diagram
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.

The circuit board used in the application should use RF circuit design techniques. Signal lines should have 50 Ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
