QuinStar Technology, Inc. - Application Notes - MMW Interferometers

Millimeter-wave (MMW) interferometers consist of a transmitter source, a receiver, and a reference channel. The local oscillator (LO) for the receiver is derived from the same source as the transmitter. Specifically, this occurs either by splitting the power from a common oscillator or by phase-locking another oscillator to the transmitter source.

Interferometers are specialized m... (read more)
