QUP Ka/Q-Band Up Converter

Objectives

The Ka/Q-Band Up Converter Programme objective is to complement and to further strengthen RSE’s converter and receiver products by performing following key development activities in Q/V Converter product area:

  • The design and development of a Ku to Q Upconverter, realized as an EM.
  • The design and development of converter mixer and PA MMICs.

Challenges

MMIC Design in Q-band (40 GHz) is challenging and will require careful modelling and optimization

The Spurious signals suppression, eg. 4xLO, is challenging, and requires use of advanced mixer topologies.

Benefits

The program will make RUAG Space competitive both in Europe and US in the product area.

Features

Key features:

  • Excellent performance
  • Low mass
  • Small size
  • Low cost

system architecture

The Converter RF chain comprises four main components:

1. Input filter

2. Mixer MMIC including buffer amplifiers

3. Output filter

4. Output amplifier MMIC

The nominal gain of mixer MMIC and output amplifier MMIC is based on a converter unit gain of typically 30 dB. The sum of the mixer and output amplifier MMICs nominal gain values gives 10 dB margin for filter and other losses/ tolerances.

A block diagram is given below.
