HMC253LC4 General Description

The HMC253LC4 is a non-refl ective SP8T switch in a leadless RoHS compliant 4x4 mm ceramic SMT package featuring wideband operation from DC to 3.5 GHz. The switch offers a single positive bias and true TTL/CMOS compatibility enabling it to operate with 0/+3V control and a +5V supply. A 3:8 decoder is integrated on the switch requiring only 3 control lines and a positive bias to select each path. The HMC253LC4 SP8T will replace multiple confi gurations of SP4T and SPDT MMIC switches.

HMC256 General Description

The HMC256 chip is a compact, 2.08 mm2, I/Q Mixer MMIC which can be used as an Image Reject Mixer (IRM) or SSB upconverter. The chip utilizes two standard Hittite double-balanced mixer cells and a Lange Coupler realized in GaAs MESFET technology. All data is with the chip in a 50 Ohm test fi xture connected via 0.025 mm (1 mil) diameter wire bonds of minimal length <0.51 mm (<20 mils). A low frequency quadrature hybrid was used to interface the MMIC IF ports to a 120 MHz IF USB output. This provides an example of the I/Q Mixer in an IRM application. The IF may be used from DC to 1.5 GHz. This I/Q Mixer is a more reliable, much smaller replacement to hybrid drop-in style I/Q Mixer assemblies.

HMC256 Maximum Ratings

RF / IF Input	+13 dBm
LO Drive	+27 dBm
Channel Temperature	150
Continuous Pdiss (T = 85 ) (derate 9.36 mW/°C above 85 )	0.61 W
Thermal Resistance (RTH) (junction to die bottom)	106.8 /W
Storage Temperature	-65 to +150
Operating Temperature	-55 to +85

HMC256 Features

High Image Rejection: >30 dB
Input IP3: +18 dB
Wideband IF: DC to 1.5 GHz
Small Size: 1.3 mm x 1.6 mm

HMC256 Typical Application

The HMC256 is ideal for:
• Microwave Radio & VSAT
• Test Instrumentation
• Military Radios Radar & ECM
• Space
