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

The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected 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.
