HMC194MS8 / 194MS8E v06.0608 GaAs MMIC SPDT SWITCH DC - 3 GHz Typical Applications The HMC194MS8 /HMC194MS8E is ideal for: • Cellular/PCS Base Stations • Portable Wireless • MMDS & WirelessLAN Features Ultra Small Package: MSOP8 High Isolation: 50 dB Positive Control: 0/+3V to 0/+7V Functional Diagram General Description The HMC194MS8 & HMC194MS8E are low-cost SPDT switches in 8-lead MSOP packages for use in applications which require high isolation between two RF paths. The devices can control signals from DC to 3 GHz and have been optimized to provide extremely high isolation with minimal insertion loss in medium and low power applications. On chip circuitry allows positive voltage control operation at very low DC currents with control inputs compatible with CMOS and most TTL logic families. RF1 and RF2 are reflective opens when “OFF”. 10 SWITCHES - SMT Electrical Specifi cations, TA = +25° C, Vctl = 0/+5 Vdc, 50 Ohm System Parameter Insertion Loss RF1 / RF2 RF1 / RF2 Frequency 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 - 2.0 GHz DC - 2.5 GHz 0.5 - 3.0 GHz 0/+5V Control 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 24 49 48 / 50 40 / 42 31 24 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 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 Control set to 0/+7V. 10 - 29 HMC194MS8/ HMC194MS8 v06.0608 GaAs MMIC SPDT SWITCH DC - 3 GHz Evaluation Circuit Board 10 SWITCHES - SMT List of Materials for Evaluation PCB 105143 [1] Item J1 - J3 J4 - J6 C1 - C3 R1, R2 U1 PCB [2] Description PC Mount SMA RF Connector DC Pin 100 pF capacitor, 0402 Pkg. 100 Ω resistor, 0402 Pkg.
