Amplifiers

We offer a suite of solid state power amplifiers:
- Outdoor SSPAs & Block Up Converters (BUCs) – Featuring a versatile chassis, field replaceable power supplies and phase combining for higher power, these products are available in C-, X- and Ku-band.
- Indoor SSPAs – Available in C-, X- or Ku-Band versions and a wide range of output power levels, our line of indoor Solid-State Power Amplifiers (SSPAs) are reliably constructed, and are designed for use in satellite uplink systems.
- Low Noise Amplifiers – C- and Ku-Band models with options for redundancy are offered. Compact design and rugged construction make them ideal for transportable applications and severe environments.
Outdoor Amplifiers & Block Up Converters (BUCs)
HPOD – Our series of High-Power Outdoor SSPAs provide a cost effective, more reliable replacement for TWT amplifiers in satcom terminals. Featuring field replaceable power supplies and redundant system control, the High-Power units were built with the user in mind. The units utilize low loss combining technique and MCP-based temperature versus gain compensation. The phase-combined systems allow the outputs of two amplifiers to be summed together for even higher power. And, with the unique approach to L-band frequency conversion, the optional “Smart BUC” functionality eliminates DC and 10 MHz from the input coax. Providing more value than competitive solutions, our base units include temperature compensation, sample ports, power monitor, field-replaceable power factor corrected supply and full remote monitor and control capabilities.

LPOD – Our extensive experience in the design of outdoor RF transceivers led to the LPOD family of BUC products’ efficient thermal and mechanical package. Recognizing the evolution of L-Band IF systems, the LPOD is designed to eliminate the traditional requirement for the modem to supply a DC power source and a 10 MHz reference to the BUCs and LNBs. The LPOD’s optional internal reference and LNB bias T greatly simplify multi-carrier operation and provide cost-effective redundant solutions. Featuring an internal power supply, internal reference, and internal LNB bias capability, the LPOD units offer very cost effective solutions for 1:1 redundant Tx and 1:1 redundant Rx requirements. And, the compact size and weight make the units ideally suited to installations with limited mounting space.

Common Applications for the Outdoor Amplifiers & BUCs:
- Construction of small “flyaway” terminals and earth stations
- Ship-borne antenna systems
- Satellite News Gathering
- Small to medium sized private networks
- Point-to-point links

Our extensive line of indoor Solid State Power Amplifiers (SSPAs) are reliably constructed, and are designed for use in satellite uplink systems. Highly power-efficient in redundant applications (available in 1:1 and 1:2 redundant configurations), they provide more cost-effective and reliable replacements for TWT amplifiers. Phase combined system redundancy is also available for greater power optimization.
The amplifiers use a low loss combining technique with microcontroller-based temperature versus gain compensation. A compact rack height makes them ideal for the construction of small flyaway terminals, remote and hub earth stations. Featuring user-friendly operation, the LCD menu display and cursor control keys simplify status monitoring and configuration.
Available in C-, X- or Ku-Band versions and a wide range of output power levels, the amplifiers are equipped with standard features that other manufacturers offer as options, including:
- Temperature compensation
- Sample ports
- Power monitor
- Rack slides
- Full remote monitor & control
Common Applications for the Indoor Amplifiers:
- Construction of small “flyaway” terminals, medium size (equivalent to Intelsat F) earth stations and hub earth stations
- Small to medium sized private networks
- Point-to-point links
