TERMINAL FUNCTIONS
DESCRIPTION
Not connected for normal operation. Amplifier bias adjustment. Do not ground this pin
or connect to any other pin.
RF amplifier bias 5 V
Ground
Logic high is high gain; logic low reduces gain by 16 dB. Normally set high.
RF output from RF amplifier
Not connected for normal operation. LO common gate bias adjustment. Do not
ground this pin or connect to any other pin.
Negative bias used for enable circuitry -5 V. This pin can be grounded if the user
does not use the UCEN pin to turnoff the amplifier. If the VNEG is grounded the
UCEN pin should be tied high.
Not connected for normal operation. LO amplifier bias adjustment. Do not ground this
pin or connect to any other pin.
LO input, positive, internally ac-coupled
LO input, negative, internally ac-coupled
Positive power for LO amplifier, 5 V
VDD supply for IF amplifier, negative, 5 V
VDD supply for IF amplifier, positive, 5 V
IF input, positive, dc-coupled, typical dc voltage is 1.2 V
