Set A/B control to 0/+5V, Vdd = +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 = +5 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 = +7V and A/B set to 0/+7V. 5. Back side paddle must be connected to RF ground. 6. A grounded coplanar waveguide PCB layout technique is recommended to achieve high isolation. The component side ground plane between RFC/grounded paddle and RF1/RF2 should be continuous, see below. There should be a continuous ground plane under component side layout. 5 For price, delivery and to place orders: Hittite Microwave Corporation, 2 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com Application Support: Phone: 978-250-3343 or apps@hittite.com HMC284AMS8G / HMC284AMS8GE v00.0612 SPDT Non-Reflective Switch DC - 3.5 GHz Switches - SPDT - SMT Evaluation PCB List of Materials for Evaluation PCB 105143 Item Description J1 - J3 PCB Mount SMA RF Connector J4 - J6 DC Pin C1 - C3 100 pF capacitor, 0402 Pkg.
