VG111-PCB2100

VG111 Product Features • • • • • The Communications Edge TM Product Information PCS/UMTS-band Variable Gain Amplifier Product Description The VG111 is a PCS / UMTS-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 +39.5 dBm output intercept point of the amplifier are maintained over the entire attenuation range, making the VG111 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 +85º C. All devices are 100% RF & DC tested and packaged on tape and reel for automated surface-mount assembly.

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 1.9 GHz.
