1. Test conditions unless otherwise noted: 25潞C, Vdd = +5 V in a tuned application circuit. Vctrl is the control voltage through a BJT transistor and a 100
惟
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.

Description
Cellular-band Variable Gain Amplifier
(tin-lead 6mm QFN package)
Cellular-band Variable Gain Amplifier
(lead-free/RoHS-compliant QFN package)
Fully Assembled Application Board
Operation of this device above any of these parameters may cause permanent damage.
This package is being phased out in favor of the lead-free/RoHS-compliant package type which is
backwards compatible for existing designs. Refer to WJPCN06MAY05TC1 on the WJ website.
