VG101
Cellular-band Variable Gain Amplifier
The Communications Edge TM
Product Information
Product Features
Product Description
Functional Diagram
• 750 – 1000 MHz bandwidth
• 28 dB Attenuation Range
• +40 dBm Output IP3
• +22 dBm P1dB
• Constant IP3 & P1dB over
attenuation range
• Single voltage supply
• Pb-free 6mm 28-pin QFN package
• MTTF > 1000 years
Applications
• Xmit & Rcv AGC circuitry for
mobile infrastructure
The VG101 is a cellular-band high dynamic range
variable gain amplifier (VGA) packaged in a low
profile Pb-free / RoHS-compliant surface-mount
leadless package that measures 6 x 6 mm square.
The +22 dBm output compression point and +40
dBm output intercept point of the amplifier are
maintained over the entire attenuation range, making
the VG101 ideal for use in transmitter and receiver
AGC circuits and as a variable gain stage following
an LNA in high dynamic range receiver front ends.
Superior thermal design allows the product to have a
minimum MTTF rating of 1000 years at a mounting
temperature of +85 ºC. All devices are 100% RF &
DC tested and packaged on tape and reel for
automated surface-mount assembly.

1. Test conditions unless otherwise noted: 25ºC, Vdd = +5 V in a tuned application circuit. Vctrl is the control voltage through a BJT transistor and a 100 Ω dropping resistor as shown in the same application circuit.
2. 3OIP measured with two tones at an output power of +5 dBm/tone separated by 10 MHz. The suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
3. The gain variation range is measured as the difference in gain with Vctrl = 0V and Vctrl = 4.5V at 0.9 GHz.

Product Information
VG101-F Mechanical Information
This package is lead-free/RoHS-compliant. It is compatible with both lead-free (maximum 260°C reflow temperature) and leaded (maximum
245°C reflow temperature) soldering processes. The plating material on the pins is annealed matte tin over copper.
Outline Drawing
Product Marking
The component will be lasermarked with a
“VG101F” designator with an alphanumeric lot
code on the top surface of the package.
Tape and reel specifications for this part will be
located on the website in the “Application
Notes” section.

1. The thermal resistance is referenced from the hottest
part of the junction to the ground tab (pin 4).
2. This corresponds to the typical biasing condition of
+5V, 150 mA at an 85° C case temperature. A
minimum MTTF of 1 million hours is achieved for
junction temperatures below 160° C.
