HMC337

GaAs MMIC SUB-HARMONICALLY

PUMPED MIXER, 17 - 25 GHz

v01.0803

General Description

Features

Functional Diagram

The HMC337 chip is a sub-harmonically pumped

(x2) MMIC mixer with an integrated LO amplifier

which can be used as an upconverter or downcon-

verter. The chip utilizes a GaAs PHEMT technology

The 2LO to RF isolation is excellent eliminating the

need for additional filtering. The LO amplifier is a

single bias (+3V to +4V) two stage design with only

-5 dBm nominal drive requirement. All data is mea-

sured with the chip in a 50 ohm test fixture con-

nected via 0.076 mm (3 mil) ribbon bonds of minimal

length <0.31 mm (<12 mils).

Integrated LO Amplifier: -5 dBm Input

Sub-Harmonically Pumped (x2) LO

High 2LO/RF Isolation: > 25 dB

Small Size: 0.97mm x 1.32mm

Typical Applications

The HMC337 is ideal for:

• 18 and 23 GHz Microwave Radios

• Up and Down Converter for

Point to Point Radios

• Satellite Communication Systems

* Unless otherwise noted, all measurements performed as downconverter, IF= 1 GHz.
