Technical Description ♦ The C- to L-band converter provides down-conversion, signal

amplification and channel filtering functions for satellite-based GNSS augmentation systems.

♦ Local Oscillator is synthesized from an external frequency reference (10 MHz) with very low phase noise

♦ The converter provides the gain control of the SBAS payload, either in fixed-gain mode (FGM) or in Automatic Level Control mode (ALC). Gain and mode control is made using a digital interface to the host.

♦ Channel filtering is realized with a combination of C-band, L-band filters and SAW filter.

Ka Band Receivers assembly Applications ♦ Telecommunication satellite payloads Main Features ♦ Assemblies of 6 Ka band Receivers ♦ Wideband frequency response ♦ Gain compensation over temperature ♦ Secondary voltages and single LO frequency

from external unit (CPSFGU) Background: Ka Rx on Nimiq 2, Amos3 and Koreasat 5 Qualification:

♦ EQM of the assy of six Receivers on O3B program completed in Q4 2011

FM unit production : ♦ 16 units (96 Rx chains) delivered for O3B in

2012 ♦ 8 units (48 Rx chains) to be delivered in 2013

(production started) Technical Description The unit is an assembly composed as follows: ♦ Six Rx hybrids:

Each Rx Hybrid Module is a hermetic, Kovar package providing gain compensated, low noise amplification in the Ka-band. The package material allows direct attachment of Alumina substrates, PHEMTs, and MMIC die.

Noise Figure is typically 2.1 dB at +25°C thanks to a discrete transistor 2-stage LNA followed by a MMIC LNA Gain stage, common to all 30 GHz receivers and LNA products by TAS-I

The mixer is a single balanced cold-HEMT MMIC mixer providing rejection of mixing products involving even LO harmonics, in particular 2xLO.

The RF/IF lineup is dimensioned to provide 65 dB min. of temperature-compensated, fixed gain.

A MMIC variable attenuator is used to

compensate overall gain. Amplifiers in the IF lineup are selected such that

the required linearity is met. In particular a power amplifier at the output, capable of 1W RF output at maximum allowed bias, but designed to achieve 28 dBm OIP3 per carrier

♦ One LO signal distribution card: The LO signal distribution towards RF Slice is

accomplished by means of a 2 symmetrical 4:1 Wilkinson Power combiner and a Branch Line. This component is using a printed circuit board using low-dielectric constant strip-line

Circuit connections with each RF slice make use of blind-mate connectors

♦ One thermal compensation circuit The compensation circuit, based on a resistor

network and a thermistor, is located on the thermal compensation circuit board. LC-based bias filtering functions for the positive and negative supply voltages are also placed on this board

Background Hybrid LNA as part of Ku Receiver: ♦ OPTUS 1D Qualification of stand-alone version with DC/DC Converter : Internal development 1Q 2007 Multi-pack FM unit production : ♦ For SB400 platform: W2A, W7,

Palapa D, W3B, W3C (al l in orbi t) ; Amos 4, W6A, W3D (delivered)

♦ For S/S Loral: TELSTAR 11L, NSS12, NSS14, Sirius 5 (all in orbit)

♦ Others: PAS 11R, PAN, Kazsat 2 (all in orbit)

Technical Description ♦ The Ku band Low Noise Amplifier operates in the range

12.75 to 14.50 GHz over selected 750 MHz bands, providing a nominal gain in the range 35 to 45 dB with a noise figure below 1.4 dB at ambient temperature. It is equipped with a low-power DC/DC converter supplying a single, well regulated secondary voltage. Both regulated 100 V and non-regulated 24 to 43 V Buses can be accommodated including high level ON/OFF commands and ON/OFF telemetry interface.

♦ The LNA Hybrid Module is a hermetic, Aluminum package providing gain compensated, low noise amplification in the Ku-band. The package material provides excellent thermal-conductivity while permitting direct attachment of Alumina substrates, PHEMTs, and MMIC die via epoxy which improves ground plane continuity at transitions. The DC/DC Converter PCB is contained in a non-hermetic, aluminum module.

♦ A discrete input stage LNA permits optimization of NF and is followed by a MMIC gain block that provides sufficient gain and linearity guaranteeing negligible degradation of NF due to successive units. An external low loss waveguide input isolator provides excellent return loss. Gain is stabilized over temperature by a simple resistor network governed by a thermistor driving a reflective PIN diode attenuator.
