HMC545 / 545E v00.0905 GaAs MMIC SPDT SWITCH, DC - 3 GHz Typical Applications The HMC545 / HMC545E is ideal for: • Cellular/3G Infrastructure • Private Mobile Radio Handsets • WLAN, WiMAX & WiBro • Automotive Telematics • Test Equipment Features Low Insertion Loss: 0.25 dB High Input IP3: +65 dBm Low DC Power Consumption Positive Control: 0/+3V to 0/+8V Ultra Small Package: SOT26 Functional Diagram General Description The HMC545 and HMC545E are low-cost SPDT switches in 6-lead SOT26 plastic packages for use in general switching applications which require very low insertion loss and very small size. With 0.25 dB typical loss, these devices can control signals from DC to 3.0 GHz and are especially suited for IF and RF applications including Cellular/3G, ISM, automotive and portables. The design provides exceptional insertion loss performance, ideal for filter and receiver switching. RF1 and RF2 are reflective shorts when “Off”. The two control voltages require a minimal amount of DC current and offer compatibility with CMOS and some TTL logic families. 10 SWITCHES - SMT Electrical Specifi cations TA = +25° C, Vctl = 0/+5 Vdc (Unless Otherwise Stated), 50 Ohm System Parameter Insertion Loss Frequency DC - 1.0 GHz DC - 2.5 GHz DC - 3.0 GHz DC - 2.2 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 Vctl = 0/+3V Vctl = 0/+5V Vctl = 0/+8V Vctl = 0/+3V Vctl = 0/+5V Vctl = 0/+8V 0.5 - 3.0 GHz 23 29 32 26 22 20 Min.

Set logic gate 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 +3V to +8V 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 = +8V and A/B set to 0/+8V. Pin Descriptions Pin Number 1, 3, 5 Function RF2, RF1, RFC Description These pins are DC coupled and matched to 50 Ohms. Blocking capacitors are required.
