FEATURES

GENERAL DESCRIPTION

Conversion gain: 15 dB typical

Sideband rejection: 22 dBc typical

The HMC7912 is a compact, gallium arsenide (GaAs), pseudo-

morphic (pHEMT), monolithic microwave integrated circuit

(MMIC) upconverter in a RoHS compliant, low stress, injection

molded plastic LFCSP package that operates from 21 GHz to

24 GHz. This device provides a small signal conversion gain of

15 dB with 22 dBc of sideband rejection. The HMC7912 uses a

variable gain amplifier preceded by an in-phase/quadrature (I/Q)

mixer that is driven by an active 2× LO multiplier. IF1 and IF2

mixer inputs are provided, and an external 90° hybrid is needed to

select the required sideband. The I/Q mixer topology reduces

the need for filtering of the unwanted sideband. The HMC7912

is a much smaller alternative to hybrid style single sideband (SSB)

upconverter assemblies, and it eliminates the need for wire

bonding by allowing the use of surface-mount manufacturing

techniques.

Input power for 1 dB compression (P1dB): 4 dBm typical

Output third-order intercept (OIP3): 33 dBm typical

2× local oscillator (LO) leakage at RFOUT: 5 dBm typical

2× LO leakage at the intermediate frequency (IF) input:

−35 dBm typical

RF return loss: 15 dB typical

LO return loss: 15 dB typical

32-lead, 5 mm × 5 mm LFCSP package
