Custom MMIC launches broadband frequency doubler spanning 7-11GHz

Monolithic microwave integrated circuit developer Custom MMIC of Westford, MA, USA has added to its growing line of broadband frequency doublers with the CMD226N3, which spans input frequencies of 7-11GHz (C- and X-band, input; Ku- and K-band output). What is claimed to be low conversion loss and high Fo isolation make it suitable for use in military radar, SMDS, SATCOM, VSAT, and LO chains for point-to-point microwave/millimeter-wave radio in cellular backhaul applications.

The gallium arsenide (GaAs)-based CMD226N3 is a x2 passive frequency multiplier that offers broadband performance and is housed in a QFN-style package. With a drive level of +15 dBm, it offers 9.0dBm of conversion loss at 18GHz and Fo isolation in reference to an input level of 44dB. The 3Fo and 4Fo isolation are at least 48dBc and 50dBc, respectively.

Extremely temperature stable, the conversion gain varies less than 2dB from nominal across the entire frequency band of operation, and is also very stable under varying drive conditions. The CMD226N3’s passive design exhibits what is claimed to be excellent phase noise performance, without the need for biasing circuitry. It also incorporates a 50 ohm matched design on chip, removing the necessity to RF port match the device.
