The CMD310 is a sub-harmonically pumped

mixer die with an integrated LO amplifier

which can be used as an upconverter or

downconverter. The device has low conversion

loss

and

excellent

2LO to RF isolation

eliminating the need for additional filtering.

The CMD310 requires only -4 dBm LO drive

and operates on a single positive supply

voltage. The sub-harmonic design and low LO

drive level allows for less stringent oscillator

requirements.

► Integrated LO amplifier

► High isolations

► Sub-harmonic ×2 LO

► Single positive supply voltage

► HMC264 replacement
