Low Insertion Loss: <0.5 dB @ 2.0 GHz Positive Control: 0/+5V Ultra Small MSOP8 Package: 14.8 mm Electrical Specifications, TA = +25° C, Vctl = 0/+5 Vdc, 50 Ohm System Typical Applications The HMC199MS8 / 199MS8E is ideal for:

  • Cellular
  • ISM Basestations
  • PCS The HMC199MS8 & HMC199MS8E are low-cost general purpose dual SPDT GaAs “bypass” switches in 8-lead MSOP packa ges co v ering DC to 2.5 GH z . These four-RF- port components integrate two SPDT switches and a through line onto a single IC. The designs provide low insertion loss of less than 0.5 dB while switching passive or active external cir- cuit 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 fi lter bypass switching and single bit attenuator switching. The HMC199MS8E is a RoHS- compliant product. Parameter Frequency Min. Typ. Max.

For price, delivery, and to place orders, please contact Hittite Microwave Corporation: Order On-line at www.hittite.com Typical Application Circuit Notes: 1. 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. 5.
