HIGH IP3 GaAs MMIC

MIXER, 450 - 500 MHz

v02.0705

General Description

Features

Functional Diagram

Input IP3: +32 dBm

Conversion Loss: 9.5 dB

Low External Part Count

Included in the HMC-DK003 Designer’s Kit

[1]

Typical Applications

High Dynamic Range Infrastructure:

• GSM 450 & GSM 480

• CDMA 450

• Private Land Mobile Radio

The HMC387MS8 & HMC387MS8E are high dynamic

range passive MMIC mixers in plastic surface mount

8 lead Mini Small Outline Packages (MSOP) covering

450 to 500 MHz. Excellent input IP3 performance

of +32 dBm for down conversion and +29 dBm for

up conversion is provided for both GSM/CDMA

based

cellular

and

Private

Land

Mobile

Radio

applications at an LO drive of +17 dBm. The mixer

also has excellent performance with as little as

+13 dBm LO drive yielding a +30 dBm input IP3.

With a 1 dB compression of +22 dBm, the RF port

will accept a wide range of input signal levels.

Conversion loss is 9.5 dB typical. The DC to 150

MHz IF frequency response will satisfy many cel-

lular

transmit

or

receive

frequency

plans.

The

HMC387MS8(E) input IP3 performance coupled with

its high P1dB rivals traditional active FET mixers while

and no DC bias.
