HMC264

v02.1007

General Description

Features

Functional Diagram

Integrated LO Amplifier: -4 dBm Input

Sub-Harmonically Pumped (x2) LO

High 2LO/RF Isolation: 40 dB

Small Size: 1.32 x 0.97 x 0.1 mm

Typical Applications

The HMC264 is ideal for:

• Microwave Point-to-Point Radios

• LMDS

• SATCOM

The HMC264 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

-4 dBm nominal drive requirement. All data is mea-

sured with the chip in a 50 ohm test fixture connected

via 0.025 mm (1 mil) diameter wire bonds of minimal

length <0.31 mm (<12 mils).
