= +25 C, Vctl = 0/+3 to +8 Vdc, 50 Ohm System
Typical Applications
The HMC197 is ideal for:
MMDS & WirelessLAN
PCMCIA Wireless Cards
Portable WIreless
The HMC197 is a low-cost SPDT switch in a
6-lead SOT26 plastic package for use in general
switching applications which require very low
insertion loss and very small size. The device
can control signals from DC to 3.0 GHz and is
especially suited for 900 MHz, 1.8 - 2.2 GHz,
and 2.4 GHz ISM applications with less than 1
dB loss. The design provides exceptional inser-
tion loss performance, ideal for fi lter and receiver
switching. RF1 and RF2 are refl ective shorts
when "Off". The two control voltages require a
minimal amount of DC current and offer compat-
ibility with most CMOS & TTL logic families. See
HMC221 for same performance in an alternate
SOT26 pin-out.

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

Typical Application Circuit
GaAs MMIC SOT26 SPDT
SWITCH, DC - 3 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 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
GaAs MMIC SOT26 SPDT
SWITCH, DC - 3 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.
