HMC484MS8G / 484MS8GE v04.0608 Typical Applications Features The HMC484MS8G / HMC484MS8GE is ideal for: High RF Power Handling:> +40 dBm • Wireless Infrastructure High Third Order Intercept: > +70 dBm • ISM/Cellular Portables/Handsets Single Positive Supply: +3 to +10 Vdc • Automotive Telematics Low Insertion Loss: 0.4 to 0.6 dB • Mobile Radio Ultra Small MSOP8G Package: 14.8 mm2 • Test Equipment Included in the HMC-DK005 Designer’s Kit Functional Diagram General Description The HMC484MS8G & HMC484MS8GE are lowcost SPDT switches in 8-lead MSOPG packages for use in transmit-receive applications which require very low distortion at high input signal power levels, through 10 watts (+40 dBm). The device can control signals from DC to 3.0 GHz. The design provides exceptional intermodulation performance; > +70 dBm third order intercept at +5 volt bias. RF1 and RF2 are reflective shorts when “OFF”. On-chip circuitry allows single positive supply operation from +3 Vdc to +10 Vdc at very low DC current with control inputs compatible with CMOS and most TTL logic families. 11 SWITCHES - SPDT T/R - SMT GaAs MMIC 10 WATT T/R SWITCH DC - 3 GHz Electrical Specifi cations, TA = +25° C, Vctl = 0/+5 Vdc, Vdd = +5 Vdc (Unless Otherwise Stated), 50 Ohm System Parameter Frequency Min.

Blocking capacitors are required. 4 Vdd Supply Voltage 6, 7 GND Package bottom must also be connected to PCB RF ground. Interface Schematic SWITCHES - SPDT T/R - SMT 11 Typical Application Circuit Notes: 1. Set logic gate and switch Vdd = +3V to +10V 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 +10 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. 11 - 138 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 HMC484MS8G / 484MS8GE v04.0608 GaAs MMIC 10 WATT T/R SWITCH DC - 3 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.
