Typical Applications
The HMC190MS8 is ideal for:
MMDS & WirelessLAN
Portable Wireless
The HMC190MS8 is a low cost SPDT switch in
an 8-lead MSOP package. The switch can con-
trol signals from DC to 3.0 GHz. It is especially
suited for low and medium power applications
using positive control voltages. The two control
voltages require a minimal amount of DC current,
which is optimal for battery powered radio sys-
tems at 0.9, 1.9, and 2.4 GHz. The HMC190MS8
design provides exceptional third order intermod-
ulation performance of +50 dBm. The design has
been optimized for the small MSOP package, and
maintains a VSWR of better than 1.2:1 up to 2
GHz. This device is the positive control MSOP8
packaged version of our HMC239S8 negative
control device.

Compression vs. Control Voltage
Caution: Do not operate in 1dB compression at power levels
above +31dBm (Vctl = +5 Vdc) and do not "hot switch" power
levels greater than +20dBm (Vctl = +5Vdc).
DC blocks are required at ports RFC, RF1 and RF2.

Typical Application Circuit
Notes:
1. Set logic gate and switch Vdd = +3V to +5V and use HCT series logic to provide a TTL driver interface.
2. Control inputs A/B can be driven directly with CMOS logic (HC) with Vdd of 5 to 8 Volts applied to the CMOS
logic
gates.
3. DC blocking capacitors are required for each RF port as shown. Capacitor value determines lowest frequency
of
operation.
4. Highest RF signal power capability is achieved with Vdd = +8V and A/B set to 0/+8V.
