Typical Applications
The HMC195 is ideal for:
MMDS & WirelessLAN
PCMCIA Wireless Cards
Portable Wireless
The HMC195 is a low-cost SPDT switch in a
6-lead SOT26 package for use in transmit or
receive applications which require very low dis-
tortion at high signal power levels. The device
can control signals from DC to 2.5 GHz and
is especially suited for 900 MHz and 1.8 - 2.2
GHz applications with less than 1 dB loss. The
design provides exceptional intermodulation per-
formance; a +62 dBm third order intercept at
8 Volt bias. RF1 and RF2 are refl ective shorts
when "Off". On-chip circuitry allows single posi-
tive supply operation at very low DC current with
control inputs compatible with CMOS and most
TTL logic families.

Compression vs. Bias Voltage
Caution: Do not operate in 1dB compression at power levels
above +33 dBm and do not "hot switch" power levels greater
than +23dBm (Vctl = +5Vdc).
DC blocks are required at ports RFC, RF1 and RF2.

Typical Application Circuit
GaAs MMIC SOT26 T/R
SWITCH, DC - 2.5 GHz
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 3 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 V set to +10V. The switch will operate properly (but at lower
RF power capability) at bias voltages down to +3V.

Evaluation Circuit Board
GaAs MMIC SOT26 T/R
SWITCH, DC - 2.5 GHz
The circuit board used in the fi nal application should
be generated with proper RF circuit design tech-
niques. 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 evalu-
ation circuit board shown above is available from
Hittite Microwave Corporation upon request.
