HMC221 / 221E v02.0700 GaAs MMIC SOT26 SPDT SWITCH, DC - 3 GHz Designer’s Kit Available Typical Applications Features The HMC221 & HMC221E is ideal for: RoHS-Compliant Product • ISM Applications Low Insertion Loss: 0.4 dB • PCMCIA Wireless Cards Ultra Small Package: SOT26 • Cellular Applications Input IP3: +45 dBm Positive Control: 0/+3V @ 10 uA SWITCHES - SMT 8 Included in the HMC-DK005 Designer’s Kits Functional Diagram General Description The HMC221 and HMC221E are low-cost SPDT switches in a 6-lead SOT26 plastic package for use in general switching applications which require very low insertion loss and very small size. These devices can control signals from DC to 3.0 GHz and is especially suited for 900 MHz, 1.8 - 2.2 GHz, and 2.4 GHz ISM applications with less than 1 dB loss. 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 most CMOS & TTL logic families. See HMC197 for same performance in an alternate SOT26 pin-out.The HMC221E is a RoHScompliant product. Electrical Specifications, TA = +25° C, Vctl = 0/+3 to +8 Vdc Parameter Min. Typ. Max.

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 5 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 Vdd = +8V and A/B set to 0/+8V. 8 - 40 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 HMC221 / 221E v02.0700 GaAs MMIC SOT26 SPDT SWITCH, DC - 3 GHz Evaluation Circuit Board SWITCHES - SMT 8 List of Materials for Evaluation PCB 101675 [1] Item Description J1 - J3 PCB Mount SMA RF Connector J4 - J7 DC Pin C1 - C3 330 pF capacitor, 0402 Pkg.
