HMC350MS8 / 350MS8E

v02.0705

General Description

Features

Functional Diagram Conversion Loss: 8.0 dB Input IP3: +27 dBm Input IP2: +45 dBm Input P1dB: +17 dBm

Electrical Specifications, T A = +25° C

Typical Applications

GaAs MMIC HIGH IP3 SINGLE-BALANCED MIXER, 0.6 - 1.2 GHz

The H MC350MS8 & H MC350MS8E are miniature single balanced mixers in 8 lead plastic surface mount packages. The passive GaAs schottky diode mixer

implements planar on chip baluns and requires no external components. The mixer can be used as an

upconverter, down converter, or modulator. The mixer provides 7.5 dB conversion loss and +25 dBm IIP3 with LO drive levels of +19 dBm at mid-band. The design was optimized for low cost high volume applications where high converter linearity is required.

The HMC350MS8 / HMC350MS8E is ideal for:? Cellular Basestations

? Cable Modems

? Fixed Wireless Access Systems

*Unless otherwise noted, all measurements performed as downconverter, IF= 100 MHz.

Evaluation PCB

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