LTC5556
1.5GHz to 7GHz Dual
Programmable Gain
Downconverting Mixer
DESCRIPTION
The
LTC
®
5556
dual programmable gain downconvert-
ing mixer is ideal for diversity and MIMO receivers that
require precise gain setting. Each channel incorporates
an active mixer and a digital IF VGA with 15.5dB gain
control range. The IF gain of each channel is programmed
in 0.5dB steps through the SPI.
Enable pins for each channel allow fast turn-on and shut-
down. A reduced power mode is also available.
The device has the same functionality as the LTC5566,
but the mixers are optimized for a higher 3GHz to 7GHz
RF frequency range and the IF is optimized for use up to
900MHz. The mixers may be used down to 1.5GHz, or up
to 8GHz with degraded performance.
