Description
M/A-COM's SW90-0004A is a SP6T absorptive pHEMT
switch with integral TTL driver. This device is in an MLP
plastic surface mount package. This switch offers excellent
broadband performance and repeatability from DC to 4
GHz, while maintaining low DC power dissipation. The
SW90-0004A is ideally suited for wireless infrastructure
applications.
1. During turn-on, the device requires an initial start up current (Icc) specified as "Turn-on Current". Once
operational, Icc will drop to the specified levels. This is not applicable to dual supply operation.
2. The DC-DC converter is guaranteed to start in 100 s as long as the power supplies have the maximum turn-on current
available for start-up.

6.
Operation of this device above any one of these
parameters may cause permanent damage.
7.
When the RF input is applied to the terminated port, the
absolute maximum power is +30 dBm.
8.
Standard CMOS TTL interface, latch-up will occur if logic
signal is applied prior to power supply.
3. NC = No Connection
4. For single supply operation VEE is internally generated and
must remain isolated from external power supplies. Gener-
ated noise is typical of switching DC-DC Converters.
5. Connections and external components shown in functional
schematic are required. 0.1F Capacitors need to be lo-
cated near pins 32 & 33.
