Functional Diagram
General Description
The HMC154S8 & HMC154S8E are low-cost SPDT
switches in 8-lead SOIC packages for use in transmitreceive applications which require very low distortion
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. The design
provides exceptional intermodulation performance;
providing a +60dBm third order intercept at 8 Volt bias.
RF1 and RF2 are reflective shorts when “Off”. On-chip
circuitry allows single positive supply operation at very
low DC current with control inputs compatible with
CMOS and most TTL logic families.

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 and to pin 4 of the RF switch.
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.

The circuit board used in the final 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.
