HMC264 is a microwave mixer chip produced by Hittite Microwave Corporation. It uses GaAs PHEMT technology and works in the frequency range of 20-32 GHz. The input LO power is -4 dBm, the Vdd voltage is +3V or +4V, and the 2LO to RF isolation is 40 dB.
The document describes the HMC264 chip as a GaAs MMIC sub-harmonically pumped (x2) mixer with an integrated LO amplifier. It is designed to operate as both an upconverter and downconverter in microwave applications such as point-to-point radios, LMDS, and SATCOM systems.
| Frequency Range, RF | 20 - 32 GHz |
|---|---|
| Frequency Range, LO | 10.5 - 16 GHz |
| Frequency Range, IF | DC - 6 GHz |
| Conversion Loss | 9 - 13 dB |
| Noise Figure (SSB) | 9 - 13 dB |
| Supply Current (Idd) | 25 - 28 mA |
| Operating Temperature | -55 to +85 °C |
The chip is ideal for Microwave Point to Point Radios, LMDS, and SATCOM.
The LO amplifier requires a nominal drive of -4 dBm and operates with a single bias supply between +3V and +4V.
A 0.025 mm (1 mil) diameter pure gold wire is recommended.
