Ku-band power amplifier with optional internal L-band BUC

By Jean-Pierre Joosting

The Model PA17-Ku400P is a traveling wave tube (TWT) power amplifier that will deliver 180-W of linear power over the 12.75 to 14.5 GHz band and offers small size and weight with less power consumption than existing amplifier products. The optional L-Band block up-converter (BUC) is an internal design that does not add to the size of the amplifier.

According to Travis Stewart, Vice President Engineering, “Satellite News Gathering (SNG) operators are looking for uplink amplifiers with lower power consumption, smaller size, less weight and more linear power. Efficiency is the driving factor in the size, weight and power (SWaP) performance of our new SATCOM uplink amplifier.”

The carbon footprint of a PA17-Ku400P is driven by the high-efficiency power conversion of the traveling wave tube, an unmatched technology for power conversion. The compact amplifier measures just 17.0 inches (43.2 cm) (L) x 8.5 inches (21.6 cm) (W) x 8.5 inches (21.6 cm) (H), and weighs 32 pounds (14.5 kg). Additional specifications include linear power of 180 W, transmit noise power of -70-dBW/4-kHz, and filter receive band of 0.65 to 12.75 GHz.

In addition, the amplifier is equipped with internal redundancy control, eliminating the need for external controller. Internal monitor and control system provides Ethernet connectivity with plug and play web page interface for out of the box use.

Tango Wave amplifier products cover Ku, DBS and Ka-band frequencies with power levels up to 750 W, including options for redundancy, power combining and BUCs. Common technology and modules, in addition to custom configurable components, offer advantages in size, weight and power over products currently available.
