1900 MHz LNA
design goals for the circuit are:
NF < 1.35 dB
Gain > 14 dB
Return Loss > 10 dB, input and output
Unconditional stability from 100 MHz to 6 GHz.
Typical performance that can be expected from this circuit at 3.0 V VCC and 5.0 mA is listed in Table 6.
The component values can be changed to enhance the performance of a particular parameter but usually
at the expense of another. Gain can be improved by sacrificing stability (R3 and R5). Input return loss can
be sacrificed to improve noise figure. Input return loss can be improved at the expense of noise figure (C3,
C7, L4). IIP3 can be improved by increasing emitter degeneration (L3) and bias current (R2). Unused
traces are available on the PCB to add emitter degeneration at leads 1 and 3 of the device.
