| HMC226 / 226E v03.0505 GaAs MMIC +3V SOT26 TRANSMIT/ RECEIVE SWITCH, DC - 2.0 GHz Designer's Kit Available Typical Applications The HMC226 / HMC226E is ideal for: * 900 MHz ISM/Cellular * 1900 MHz PCS Features Low Insertion Loss: 0.6 dB Ultra Small Package: SOT26 High Input P1dB: +35 to +38 dBm High Input IP3: +55 to +61 dBm 8 SWITCHES - SMT Functional Diagram Positive Control: 0/+3V to 0/+8V Included in the HMC-DK005 Designer's Kit General Description The HMC226 & HMC226E are low-cost SPDT switches in 6-lead SOT26 packages for use in transmit-receive applications which require very low distortion at high signal power levels. The device can control signals from DC to 2.0 GHz and is especially suited for 450 MHz, 900 MHz, and 1.8 - 2.0 GHz applications with 0.5 to 0.8 dB loss. The design provides exceptional P1dB and intermodulation performance; a +35 dBm 1dB compression point and +55 dBm third order intercept at +3 volt bias. RF1 and RF2 are reflective opens 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.

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 8 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 V set to +10V. The switch will operate properly (but at lower RF power capability) at bias voltages down to +3V. 8 - 52 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC226 / 226E v03.0505 GaAs MMIC +3V SOT26 TRANSMIT/ RECEIVE SWITCH, DC - 2.0 GHz Evaluation Circuit Board 8 SWITCHES - SMT List of Materials for Evaluation PBC 101675 [1] Item J1 - J3 J4 - J7 C1 - C3 U1 PCB [2] Description PCB Mount SMA RF Connector DC Pin 330 pF capacitor, 0402 Pkg.
