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.
IF input, negative, dc coupled Typical dc voltage is 1.2 V.
Output of mixer (after balun) 50
impedance with high impedance DC ground.
Set HIGH to enable IF amplifier and RF amplifiers
Normally grounded. Provide 0
jumper to ground.
Not connected for normal operation. IF amplifier bias adjustment. Do not ground this pin or
connect to any other pin.
Positive supply for IF bias circuitry +5 V
Input to RF amplifier, 50
impedance, Internally AC coupled
RF amplifier bias +5 V
Back of package has metal base that must be grounded for thermal and RF performance.
