PRODUCT DESCRIPTION
The AWS5508 SP4T high power antenna switch is
designed to operate in the GSM 900Mhz, DCS
1800MHz, and PCS 1900MHz frequency bands. All 4
ports of the switch have identical electrical and
linearity performance which allows flexibility in
system design. Switching between ports is
accomplished using 2.7 to 6 volts differential control
voltages on the 4 control pins. The switch is provided
in a leadless MLP-16 quad flat package.
1. DC blocking capacitors C
b
and optional
resistor Rs must be supplied externally.
2. C
b
= 100 pF for operation >500MHz.
3. The use of resistor Rs to the positive
voltage supply is optional. It is only required
if it is necessary to have all RF ports in Isolation
state at the same time. Also, using Rs will improve
linearity performance to a small degree when V
CTL
is at its lower limit. Rs = 10k
