ADVANCED PRODUCT INFORMATION - Rev 0.3

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.

PIN 1 INDICATOR

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

when used.
