L, S- BAND SPDT SWITCH
DESCRIPTION
The
µ
PG158TB is a L-band SPDT (Single Pole Double Throw) GaAs FET switch which was developed for digital
cellular, cordless telephone and other L, S-band wireless application. The device can operate from 500 MHz to 2.5
GHz, having the low insertion loss. It housed in an original 6-pin super minimold package that is smaller than usual
6-pin minimold easy to install and contributes to miniaturizing the system.

Notes 1.

P
in(0.1 dB)
or P
in(1 dB)
is measured the input power level when the insertion loss increases more 0.1 dB or
1 dB than that of linear range. All other characteristics are measured in linear range.
Cautions 1.
When the
µ
PG158TB is used it is necessary to use DC blocking capacitors for No. 1 (OUT1),
No.3 (OUT2) and No.5 (IN).
The value of DC blocking capacitors should be chosen to
accommodate the frequency of operation, band width, switching speed and the condition
with actual board of your system.
The range of recommended DC blocking capacitor value is less than 100 pF.
2.
The distance between IC’s GND pin and ground pattern of substrate should be as shorter as
possible to avoid parasitic parameters.
