HMC260

GaAs MMIC FUNDAMENTAL

MIXER, 14 - 26 GHz

Features

Passive: No DC Bias Required
Input IP3: +20 dBm
LO/RF Isolation: 39 dB
Small Size: 0.55mm

General Description

The HMC260 is a passive double balanced mix er
that can be used as an upconverter or down­converter between 14 and 26 GHz. The minia­ture monolithic mixer (MMIC) requires no external
components or matching circuitry. The HMC260
provides excellent LO to RF and LO to IF sup­pression due to optimized balun structures. The
mixer operates with LO drive levels above +9
dBm. Measurements were made with the chip
mounted and bonded into in a 50 ohm test fi xture.
Data includes the parasitic effects of wire bond
assembly. Connections were made with a 3 mil
ribbon bond with minimal length (<12 mil).
