HMC197

HMC197 / 197E v02.0505 GaAs MMIC SOT26 SPDT SWITCH, DC - 3 GHz Typical Applications The HMC197 / HMC197E is ideal for: • MMDS & WirelessLAN • PCMCIA Wireless Cards • Portable WIreless Features Low Insertion Loss: 0.4 dB Ultra Small Package: SOT26 Input IP3: +45 dBm Positive Control: 0/+3V @ 10 uA 8 SWITCHES - SMT Functional Diagram General Description The HMC197 & HMC197E 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. The device 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 HMC221 for same performance in an alternate SOT26 pin-out.

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 - 28 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 HMC197 / 197E v02.0505 GaAs MMIC SOT26 SPDT SWITCH, DC - 3 GHz Evaluation Circuit Board 8 SWITCHES - SMT List of Materials for Evaluation PCB 101674 [1] Item J1 - J3 J4 - J6 C1 - C3 U1 PCB [2] Description PCB Mount SMA RF Connector DC Pin 330 pF capacitor, 0603 Pkg.
