Overview
The HMC264 is a sub-harmonically pumped (x2) Monolithic Microwave Integrated Circuit (MMIC) mixer designed and manufactured by Analog Devices Inc. This component is integrated with an LO (Local Oscillator) amplifier and can be used as either an upconverter or a downconverter. The HMC264 utilizes GaAs PHEMT (Pseudomorphic High Electron Mobility Transistor) technology, resulting in a compact chip size of 1.32 x 0.97 x 0.1 mm.
This mixer operates within the frequency range of 20 to 32 GHz, making it suitable for various high-frequency applications. The device is known for its high 2LO/RF isolation of 40 dB and its small size, which is beneficial for space-constrained designs.
