Mnemonic Description
1
INLO
Detector Common. This pin should be ac-coupled to ground.
2
INHI
Detector Input. When operating in AGC mode, a portion of the signal at the output of the VVA (or at the
output of a subsequent stage) is coupled back to this input. The signal should be ac-coupled into INHI. To provide
a 50 Ω match at INHI, a 50 Ω resistor should be connected between INHI and ground (with the ac-coupling
capacitor placed between the resistor and the INHI pin).
3
VSET
Setpoint Input. Setpoint input for controller mode or feedback input for measurement mode.
4
CLPF
AGC Loop Filter Capacitor. The ground-referenced capacitor that is connected to this pin sets the loop bandwidth
of the AGC circuit.
5, 11, 13, 15, COMM
16, 18, 19, 27,
28, 31, 32, 40
Device Common. Connect these pins to the same low impedance ground plane.
6
VREF
Attenuator Control Voltage Reference. In AGC mode, this pin should be left open. In open-loop mode, when
the VVA is being controlled externally, a 2 V reference voltage should be applied to this pin.
7
VDET/VCTL Detector Output/VVA Control Voltage Input. When the VVA is being controlled externally (open-loop mode),
the attenuation is controlled by the external voltage applied to this pin. The VVA control range is from 0 V
(maximum attenuation) to 2 V (minimum attenuation). In this mode, VREF (Pin 6) should be tied to approximately
2 V. When the VVA is being operated in AGC mode, this pin is left open with the voltage on the pin representing the
AGC drive voltage to the VVA. If the VVA is not being used, the AGC log amp can be used as a standalone detector
by connecting this pin to VSET. In this mode, the log amp output voltage is available at this pin.
8
TEMP
Temperature Sensor Output. This pin provides a standalone temperature sensor output voltage. At room
temperature, the nominal output voltage is equal to 1.45 V. The slope of the output voltage is equal to 4.6 mV/°C.
9
NC
No Connect. Do not connect this pin.
10
MODOUT RF Output of IQ Modulator. Single-ended, 50 Ω internally biased RF output. MODOUT is generally
ac-coupled to the input of the VVA (either ATTI or ATTO).
12, 20
ATTI, ATTO VVA RF Input/Output. ATTI is normally ac-coupled to MODOUT. However, because the VVA is completely reversible,
MODOUT can also drive ATTO with ATTI operating as the VVA output.
14, 17
ATTCM
VVA Input/Output Common. These pins should be ac-coupled to ground.
21 to 23,
35 to 38
VPOS
Power Supply. Positive supply voltage pins. All pins should be connected to the same supply (VS). To ensure
adequate external bypassing, connect a 0.1 μF capacitor between each pin and ground.
