MMIC I/Q mixer uses fewer components and a has small PCB footprint

10-01-2020 | Analog Devices | Semiconductors

Analog Devices HMC8192 MMIC I/Q Mixer is a passive, wideband, I/Q, MMIC that can be employed either as an image rejection mixer for receiver operations or as a single-sideband upconverter for transmitter operations. With an RF and LO range of 20GHz to 42GHz and an IF bandwidth of DC to 5GHz, the device is excellent for applications demanding a wide frequency range, superior RF performance, and uncomplicated design with fewer components and a small PCB footprint. A single HMC8192LG can replace multiple narrow-band mixers in a design.


The inherent I/Q architecture of the device gives superior image rejection, excluding the requirement for expensive filtering for unwanted sidebands. The mixer also gives excellent LO to RF and LO to IF isolation and decreases the effect of LO leakage to assure signal integrity.


As a passive mixer, the device does not need any DC power sources. The device provides a lower noise figure compared to an active mixer, assuring superior dynamic range for high performance and precision applications.


The device is fabricated on a GaAs, MESFET process and uses the company's mixer cells and a 90-degree hybrid. The device is offered in a compact, 4mm x 4mm, 25-terminal LGA_CAV package and operates over a -40C to +85C temperature range.
