CXG1092N
Application Note (1)
Impedance matching for harmonic minimization
To achieve the 2nd harmonic levels lower than
–
36dBm for GSM900
Design of 1.8GHz harmonic matching network and the 900MHz trap network is dependent on the board design
and components.

Technique
Allows use of the CXG1092N (SP5T) in handsets
with 3V min. battery voltage (2.7V SW supply).
The CXG1092N is for 5V nominal battery voltage
but work well down to 4V.
Fundamentally, the 577
μ
s time slot waveform is
used to increase the 2.7V supply to over 4V.
This waveform may be taken from the PA
ramping input (or drain supply in case of drain
power control) or via the TX ON/OFF logic.
