More Information
1) Measurement conditions are as follows: T = 25°C, VCC = 6 V, Freq. = 900 MHz, 50 ohm system.
2) S11 & S22 can be improved, at a specific frequency, by moving an input shunt capacitor (C2) along an input transmission line.
3) OIP3 is measured with two tones at an output power of +8 dBm/tone separated by 1 MHz.
4) The thermal resistance was determined at a DC power of 0.834 W (VCC=6 V, IC=139 mA) with RF signal and a lead temperature of
85.2 °C.

Note: 1. The number and size of ground via holes in a circuit board is critical for thermal
and RF grounding considerations.
2. We recommend that the ground via holes be placed on the bottom of lead pin 2 for
better RF and thermal performance, as shown in the drawing at the left side.
