RFAGC
RF Gain select voltage input. The voltage applied to this pin sets the gain of
the RF amplifier. The voltage applied to this pin should be between 0.5V
and 4.5V. The RF gain characteristic is such that 0.5V yields a gain of -2dB
and 4.5V yields a gain of +30dB as measured from the input of the LNA to
the output of the mixer stage.
13
LO
Differential LO Input. This pin and pin 14 (LOB) are the differential LO
inputs. This input should be AC-coupled. The differential input impedance
across pins 13 and 14 is 75
Ω. The LO may be driven single ended but will
require a higher drive level. If a single ended LO is applied, pin 14 should
be AC-coupled to ground.
14
LOB
Complementary LO Input. Should be AC-coupled.
15
GND
Ground.
16
RFVCC
5V supply for RF section.
GND
Paddle
Backside of package should be connected to ground.
