Thomson Debuts New RF Synthesizer
|
Thomson Broadcast announced a new APS RF synthesizer for its analog and
DRM shortwave transmitters.
The synthesizer has an
adaptive precorrection stage for compensating for weaknesses in the broadcast
chain. It will also adjust for differences between antennas in multiple antenna
arrays.
An additional feature is ripple compensation
that Thomson says will result in passband ripple of less than 0.1 dB. Overall,
according to Thomson, analog users should see improvements in linearity and
frequency response. Digital broadcasters should see better MER and spectral
purity.
Thomson Broadcast Managing Director Josef
Troxler stated: “The APS system is a new development for our high-power
shortwave transmitter business … Now our customers can upgrade their existing
transmitters with adaptive precorrection to get the best signal quality and
yield even better function.”
