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.

2. C

= 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.

1.

system.
2.
Video feedthru measured with 1 ns risetime pulse and 500MHz bandwidth.
3.
VCTL is the differential voltage between any one of the control pins (V1 through V4) and the remaining three
control pins. Changing which control pin is the most positive voltage selects the switch path as defined in the
truth table below. Use of the optional resistor Rs on the common port limits VHigh to Vs 0.2V.

Notes:
1. Control Voltage is the diffenterial voltage between any of pins V1,
V2, V3, V4 and RFc.
Stresses in excess of the absolute ratings may cause permanent
damage. Functional operation is not implied under these
conditions. Exposure to absolute ratings for extended periods
of time may adversely affect reliability.
