HMC224MS8 / 224MS8E v02.0805 GaAs MMIC T/R SWITCH 5 - 6 GHz D E U N I T N O T C C S U I D D O PR Typical Applications Features The HMC224MS8 / HMC224MS8E is ideal for: Low Cost 5-6 GHz Switch • UNII & HiperLAN Ultra Small Package: MSOP8 • PCMCIA WirelessLAN High Input P1dB: +33 dBm ns g i s De Single Positive Supply: +3 to +8V Functional Diagram ew N r fo d e d Description enGeneral m The HMC224MS8 & HMC224MS8E are low-cost com e R SPDT switches in 8-lead MSOP packages for use in t No transmit-receive applications. The device can control signals from 5.0 to 6.0 GHz and is especially suited for 5.2 GHz UNII and 5.8 GHz ISM applications with only 1.2 dB loss. The design provides exceptional power handling performance; input P1dB = +33 dBm at 5 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. No DC blocking capacitors are required on RF I/O ports. SWITCHES - SPDT T/R - SMT 11 Electrical Specifi cations, TA = +25° C, Vdd = +5 Vdc, 50 Ohm System Parameter Frequency Typ. Max.

Set V to 5 Volts and use HCT series logic to provide a TTL driver interface. Highest RF signal power capability is achieved with V set to +10V. However, the switch will operate properly (but at lower RF power capability) at bias voltages down to +3V. RF ByPass: Do not use RF bypass capacitors on Vdd, A or B ports. Resistors R1, R2, R3 = 100 Ohms should be placed close to the Vdd, A and B ports. Use resistor size 0402 to minimize parasitic inductances and capacitances. DC Blocking capacitors are not required for each RF port. Evaluation PCB available.
