| MICROWAVE CORPORATION v02.0701 HMC270MS8G GaAs MMIC SPDT SWITCH NON-REFLECTIVE, DC - 8.0 GHz Features Broadband Performance: DC - 8 GHz Very High Isolation: 45 dB @ 6 GHz Non-Reflective Design Low Cost MSOP-8 Package: 14.8 mm2 Typical Applications The HMC270MS8G is ideal for DC - 8.0 GHz applications: * CATV * MMDS & WirelessLAN * Wireless Local Loop Functional Diagram General Description The HMC270MS8G is a broadband non-reflective GaAs SPDT switch in an 8 lead MSOP grounded base surface mount plastic package. Covering DC to 8 GHz, the switch offers excellent isolation from 70 to 35 dB. The negative control voltage of -5 volts allows operation down to DC. If positive control is required along with high isolation, see the DC to 3.5 GHz HMC284MS8G non-reflective SPDT. 14 SWITCHES - SMT Electrical Specifications, TA = +25 C, With 0/-5V Control, 50 Ohm system Parameter Frequency DC - 2.0 GHz DC - 6.0 GHz DC - 8.0 GHz DC - 2.0 GHz DC - 4.0 GHz DC - 6.0 GHz DC - 8.0 GHz DC - 2.0 GHz DC - 6.0 GHz DC - 8.0 GHz DC - 2.0 GHz DC - 6.0 GHz DC - 8.0 GHz 0.5 - 8.0 GHz 0.5 - 8.0 GHz DC - 8.0 GHz 20 50 ns ns 43 42 37 28 11 9 7 15 13 10 20 33 Min.

These are optional resistors. 14 SWITCHES - SMT 14 - 149 List of Materials Item J1 - J3 J4 - J5 Description PC Mount SMA Connector DC Pin Chip Capacitor, 0402 Pkg, choose value for lowest frequency of operation. PCBs are provided with 100 ~ 300 pF capacitors. User may jumper capacitor mounting gaps on PCB to allow operation to "DC". 100 Ohm Resistor, 0402 Pkg. HMC270MS8G SPDT Switch 102807 Evaluation PCB 2.0" x 2.6" C1 - C3 The circuit board used in the final application should be generated with proper RF circuit design techniques. Signal lines at the RF ports should have 50 ohm impedance and the package ground leads and exposed ground paddle 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.
