| MICROWAVE CORPORATION v03.0404 HMC199MS8 DUAL SPDT SWITCH DC - 2.5 GHz Features Integrated Dual SPDTs Low Insertion Loss: <0.5 dB @ 2.0 GHz Positive Control: 0/+5V Ultra Small MSOP8 Package: 14.8 mm2 Typical Applications The HMC199MS8 is ideal for: * Cellular * ISM Basestations * PCS Functional Diagram General Description The HMC199MS8 is a low-cost dual SPDT GaAs "bypass" switch in an 8-lead MSOP package covering DC to 2.5 GHz. This four RF port component integrates two SPDT switches and a through line onto a single IC. The design provides low insertion loss of less than 0.5 dB while switching passive or active external circuit components in and out of the signal path. Port to port isolations are typically 25 to 30 dB. On-chip circuitry enables positive voltage control operation at very low DC currents with control inputs compatible with CMOS and most TTL logic families. Applications include LNA or filter bypass switching and single bit attenuator switching. 14 SWITCHES - SMT Electrical Specifications, TA = +25 C, Vctl = 0/+5 Vdc, 50 Ohm System Parameter Frequency DC - 1.0 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 2.0 GHz DC - 2.5 GHz DC - 2.0 GHz DC - 2.5 GHz 0.5 - 2.0 GHz 0.5 - 2.0 GHz DC - 2.5 GHz 20 40 ns ns 22 17 17 12 19 32 Min.

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 to 7 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.
