General Description
Features
Functional Diagram
Low Insertion Loss: 0.4 dB
Ultra Small Package: MSOP8
High Input IP3: +50 dBm
Positive Control: 0/+3V @ 3 µA
Electrical Specications, TA = +25° C, Vctl = 0/+3 to +8 Vdc
Typical Applications
The HMC190AMS8(E) is ideal for:
• MMDS & WirelessLAN
• Portable Wireless
The HMC190AMS8(E) is a low cost SPDT switch
in a 8-lead MSOP package. The switch can control
signals from DC to 3 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 systems at 0.9, 1.9, and
2.4 GHz. The HMC190AMS8(E) provides excep-
tional third order intermodulation 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 1 dB compression at power levels above +31 dBm (Vctl = +5 Vdc) and do not “hot switch” power levels
greater than +20dBm (Vctl = +5 Vdc).
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.

Evaluation Circuit Board
The circuit board used in the nal application
should be generated with proper RF circuit design
techniques. Signal lines at the RF port should have
50 Ohm impedance and the package ground leads
and package bottom should be connected directly
to the ground plane similar to that shown above. The
evaluation circuit board shown above is available
from Hittite Microwave Corporation upon request.
