HMC784MS8GE v00.0808 GaAs MMIC 10 WATT T/R SWITCH DC - 4 GHz Typical Applications Features The HMC784MS8GE is ideal for: Input P1dB: +40 dBm @ Vdd = +8V * Cellular / 4G Infrastructure High Third Order Intercept: +62 dBm * WiMAX, WiBro & Fixed Wireless Positive Control: +3 to +8 V * Automotive Telematics Low Insertion Loss: 0.4 dB * Mobile Radio MSOP8G Package: 14.8 mm2 * Test Equipment General Description Functional Diagram The HMC784MS8GE is a high power SPDT switch in an 8-lead MSOPG package for use in transmit-receive applications which require very low distortion at high input signal power levels. The device can control signals from DC to 4 GHz. The design provides exceptional intermodulation performance; > +60 dBm third order intercept at +5V bias. RF1 and RF2 are reflective shorts when "OFF". On-chip circuitry allows single positive supply operation from +3 Vdc to +8 Vdc at very low DC current with control inputs compatible with CMOS and most TTL logic families.

Interface Schematic Typical Application Circuit SWITCHES - SPDT - SMT 11 Pin Number Notes: 1. Set logic gate and switch Vdd = +3V to +8V 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 +8V. The switch will operate properly (but at lower RF power capability) at bias voltages down to +3V. 11 - 230 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC784MS8GE v00.0808 GaAs MMIC 10 WATT T/R SWITCH DC - 4 GHz Evaluation Circuit Board List of Materials for Evaluation PCB 104124 [1] Item Description J1 - J3 PCB Mount SMA RF Connector J4 - J7 DC Pin C1 - C3 100 pF capacitor, 0402 Pkg.
