Ground Pins
Programmable-Gain Amplifier (PGA) +5V Supply. Bypass this pin to GND1 with a decoupling capacitor as
close to the part as possible.
PGA RF Ground. As with all ground connections, maintain the shortest possible (low-inductance) length to
the ground plane.
Positive PGA Input. Along with VIN-, this port forms a high-impedance differential input to the PGA. Driving
this port differentially will increase the rejection of second-order distortion at low output levels.
Negative PGA Input. When not used, this port must be AC-coupled to ground. See VIN+.
Serial-Interface Enable. TTL-compatible input. See Serial Interface section.
Serial-Interface Data. TTL-compatible input. See Serial Interface section.
Serial-Interface Clock. TTL-compatible input. See Serial Interface section.
Shutdown. When this pin and TXEN (pin 18) are set low, all functions (including the serial interface) are dis-
abled, leaving only leakage currents to flow.
No Connection
RF Output Bypass. This pin must be bypassed to ground with a 0.1µF capacitor.
Negative Output. Along with VOUT+, this port forms a 300Ω impedance output. This port is matched to a
75Ω load using a 2:1 transformer.
Positive Output. See VOUT-.
Transmit-Disable (Enable) Timing Capacitor. See Ramp Generator section.
Power-Amplifier Enable. Setting this pin low shuts off the power amplifier.
Power Amplifier Bias, +5V Supply. Bypass this pin to GND2 with a decoupling capacitor as close to the part
as possible.
Power Amplifier Bias Ground. As with all ground connections, maintain the shortest possible (low induc-
tance) length to the ground plane.
