1. Test conditions unless otherwise noted: 25潞C, Vsupply = +5 V, in tuned application circuit. Vctrl
is the control voltage through the 120
惟
dropping resistor as shown in the application circuit on page 2.
2. Specifications refer to the device at the maximum gain setting (Vctrl=0V). The input and output
return loss will be dramatically improved with an attenuation setting greater than 1 dB.
3. 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.
4. The gain variation range is measured as the difference in gain with Vctrl = 0 and 4.5V at 800 MHz.
5. This voltage refers to the V
CTRL
as shown in the circuit schematic on page 2. There should be a
series resistance of 120鈩?between the control voltage and pin 8 for proper operation.
