DATA SHEET AV109-73, AV109-73LF: GaAs IC 35 dB Voltage Variable Attenuator Single Positive 3 V Control 0.8–1 GHz Features ● NEW VS CBL VC CBL 4 The AV109-73 GaAs IC FET voltage variable attenuator provides 35 dB attenuation range at 900 MHz controlled by a single positive voltage. The VVA has a linear transfer curve of 12 dB/V slope, with input and output VSWR better than 2:1 over all states. It operates with supply voltage of 3 V and control voltage of 0 V to 3 V in a low-cost SOT-6 package. The RF ports require 25 pF DC blocking capacitors. In addition, an external grounding capacitor is required. 5 Description 6 ● GND 3 ● J1 2 ● 1 ● Pin Out Single positive 3 V control voltage 35 dB attenuation range @ 0.9 GHz Excellent linearity performance Negative transfer slope Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020 CBP J2 GND DC blocking capacitors (CBL) and RF bypass capacitors (CBP) supplied externally. CBL = 25 pF for 900 MHz operation. CBP = 38 pF for 900 MHz operation. Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty. CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions must be employed at all times. 0.074 (1.90 mm) Ref. 0.126 (3.20 mm) 0.087 (2.20 mm) Pin 6 0.071 (1.80 mm) 0.052 (1.30 mm) Pin 1 Indicator Pin 1 0.037 (0.95 mm) Ref. 0.020 (0.51 mm) 0.014 (0.350 mm) 0.006 (0.15 mm) 0.000 (0.00 mm) 0.057 (1.45 mm) 0.035 (0.90 mm) 5.0° ± 1° 5.0° ± 1° 0.122 (3.10 mm) 0.106 (2.70 mm) 0.022 (0.61 mm) 0.004 (0.10 mm) Recommended Solder Reflow Profiles Refer to the “Recommended Solder Reflow Profile” Application Note.
