Development of the IF2 Chain for the FPU of the HIFI Instrument

Alexander Megej

April 15th, 2003, Groningen


Introduction I Instrument

  • Second Stage of the IF-Amplification Chain


Introduction II Instrument

Two different amplifier types:

  • Bands 15 (4  8 GHz)

  • Bands 6H&L(4  8 GHz)


Activities Planned Instrument

  • LNA Design

    • 2 stage LNA for the altered frequency range of the Band 6 √

    • 3 stage LNA for the Bands 1-5 (4  8 GHz) √

  • Re-design of signal combiners

    • Soft substrate: RT6002 of Rogers (SRON). √

    • Alternative: TMM10i with the existing ETH design √

  • Development and testing of amplifiers to be completed by the end of 2002 √

  • SRON performs mechanical design of the IF-2 box in co-operation with Mecom, NL √

  • ITT-Package definition √

  • Design and technology transfer to an industrial partner starting in 2003 


LNA for Bands 1 Instrument5

Three-stage design using TRW InP HEMTs


LNA for Bands 1 Instrument5


LNA for Bands 1 Instrument5


LNA for Bands 1 Instrument5

Summary of Measured Results

The employment of the isolators at the IF-2 input can be avoided


LNA for Bands 6 H&L Instrument

Two-stage design using TRW InP HEMTs


LNA for Bands 6H&L Instrument


LNA for Bands 6 H&L Instrument

Summary of Measured Results

Three-stage design required


LNA for Bands 6 H&L Instrument

Three-stage design required


Current Status I Instrument

ETH3DHI02

ETH3DLI01


Current Status II Instrument


Further Activities Instrument

  • Manufacturing of the Final Amplifier DMs

  • Issue of ITT

  • Assembling of the IF-2 DM

  • Transfer of the Design and Technology to an Industrial Partner
