Multi-Band Loop Test Translators
Atlantic Microwave Limited is pleased to announce Test Translators
for alignment of ground stations to multiple satellite transponders.
Designed to simulate the satellite link during ground station set-up and
alignment, new models of Loop Test Translator from Atlantic Microwave
Ltd. feature switchable frequency bands, thereby accommodating multiple
transponders or multiple satellites within a single 1U rack unit.
In addition to significant equipment cost savings, these translators provide
both a reduction in valuable rack space usage and an improvement in test
routine workloads for both fixed and mobile satellite stations where efficient
operation is key to economic success.
A dedicated multiple Ku band unit has the ability to translate a common
13.75~14.50GHz uplink into four separate downlink bands of 10.70~11.45GHz,
10.95~11.70GHz, 11.45~12.2GHz and 12.0~12.75GHz enabling set-up to take
place at most locations for the majority of the World’s Ku band
broadcast and telecommunication satellite links.
Alternatively, mixed Ku and C band units are available for convenient
alignment where both types of transponder are being addressed from co-located
transmit / receive equipment.
In each case, the frequency conversion is achieved with the use of custom
double balanced mixer technology driven by crystal controlled phase locked
oscillators with better than +/-2ppm frequency stability and typical phase
noise of –125dBc/Hz at 10KHz offset from the LO frequency.
Input signal level is controllable over a 30dB range by an easy-access
front panel mounted manual attenuator with vernier dial so it can be quickly
and repeatedly re-set. The rear panel RF input and output are via durable
stainless steel SMA connectors and the whole assembly measures just 13.5”
(343mm) deep in a 1U x 19” rack case.
