Condition
T = 25°C, VCC=3.6V, RF=1959MHz,
LO=1749MHz @ +1 dBm
1kΩ balanced load, 2.5dB Image Filter Loss.
Single Sideband
The LNA section may be left unused. Power
is not connected to pin 1. The performance
is then as specified for the Second Section
(Mixer).
Input is internally matched for optimum noise
figure from a 50Ω source.
IP3 may be increased 10dB by connecting
pin 22 to VCC through the matching inductor.
The LNA’s current then increases by 10mA.
Other in-between IP3 versus ICC trade-offs
may be made. See pin description for pin 20.
