v01.0101 MICROWAVE CORPORATION HMC174MS8 GaAs MMIC T/R SWITCH DC - 3 GHz Features Ultra Small Package: MSOP8 High Third Order Intercept: +60 dBm Single Positive Supply: +3 to +10V High RF power Capabilty Typical Applications The HMC174MS8 is ideal for: * ISM Applications * PCMCIA Wireless Cards * Portable Wireless Functional Diagram General Description The HMC174MS8 is a low-cost SPDT switch in an 8-lead MSOP package for use in transmitreceive applications which require very low distortion at high signal power levels. 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 only 0.5 dB loss. The design provides exceptional intermodulation performance; providing a +60 dBm 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. 14 SWITCHES - SMT Electrical Specifications, TA = +25 C, Vdd = +5 Vdc, 50 Ohm System Parameter Frequency DC - 1.0 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 3.0 GHz DC - 1.0 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 3.0 GHz DC - 1.0 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 3.0 GHz 0/8V Control 0.5 - 1.0 GHz 0.5 - 3.0 GHz 0.5 - 1.0 GHz 0.5 - 3.0 GHz DC - 3.0 GHz tRISE, tFALL (10/90% RF) tON, tOFF (50% CTL to 10/90% RF) 10 24 ns ns 22 20 17 13 20 16 13 9 35 34 55 55 Min.

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. 14 - 24 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 12 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com MICROWAVE CORPORATION v01.0101 HMC174MS8 GaAs MMIC T/R SWITCH DC - 3 GHz Evaluation Circuit Board 14 SWITCHES - SMT 14 - 25 List of Material Item J1 - J3 J4 - J7 C1 - C3 C4 U1 PCB* Description PC Mount SMA RF Connector DC Pin 100 pF capacitor, 0402 Pkg. 10,000 pF capacitor, 0603 Pkg. HMC174MS8 T/R Switch 104122 Evaluation PCB 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. * Circuit Board Material: Rogers 4350 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 12 Elizabeth Drive, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order Online at www.hittite.com |
