GENERAL DESCRIPTION
The ADMV7420 is a fully integrated system in package (SiP) in
phase/quadrature (I/Q) downconverter that operates between
an intermediate frequency (IF) output range of dc and 2 GHz
and a radio frequency (RF) input range of 81 GHz and 86 GHz.
The device provides a small signal conversion gain of 10 dB
with 30 dBc of image rejection. The ADMV7420 uses a low
noise amplifier followed by an image rejection mixer that is
driven by a 6× local oscillator (LO) multiplier. Differential I and
Q mixer outputs are provided for direct conversion applications.
Alternatively, the outputs can be combined using an external
90° hybrid and two external 180° hybrids for single-ended
applications.
The ADMV7420 comes in a fully integrated, surface-mount,
34-terminal, 11 mm × 13 mm, chip array small outline no lead
cavity (LGA_CAV) package. The ADMV7420 operates over the
−40°C to +85°C case temperature range.
