Features and Benefits
- Integrated LO Amplifier: -4 dBm Input
- Sub-Harmonically Pumped (x2) LO
- Integrated IF Amplifier: 3 dB Gain
- Small Size: 1.32 x 1.32 x 0.1 mm
The HMC265 chip is a sub-harmonically pumped (x2) MMIC downconverter with integrated LO & IF amplifiers. The chip utilizes a GaAs PHEMT technology that results in a small overall chip area of 1.74 mm². 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 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). This downconverter IC is an excellent, smaller, and more reliable replacement to hybrid diode based downconverter MMIC assemblies.
