20-25W Ka-Band Power Amplifiers

Sophia Wireless

25-31 GHz Outdoor SSPA Product Line

Solid State Power Amplifier

Product Description:

The MPC4-1530 ODU Series provides an unparalleled size, weight, & power combination. The Series has a multitude of configurations that can meet your specific needs. The models are defined by the Communication bands + RF power levels 20W or 25W, + optional features 04 (L-Band Block Up-Converter), and 09 (28 & 48V DC power supply). The features & options are ideal for SATCOM systems serving military & commercial airborne
& mobile platforms.

Size: 10.3" x 8.98" x 10.262"
Weight: <26 lbs.

Performance Features:

Sophia's MPC4-1530 Series provides high data rate systems with up to 25 watts of power and 50 dB
of gain. Temperature compensation circuitry minimizes gain & power variations. The outdoor
enclosure includes a 115/230V AC power supply, and a forced air cooling system. Smart sensors in
the RF assembly and power supply provide thermal & bias protection, and a monitor and control
circuit provides critical performance status for initial system integration and field use.

Monitor & Control Functions:

The monitor & control processor interfaces with a host computer. All voltage, current, power, and
temperature sensors are read through this interface. The discrete mute control is opto-isolated for
trouble-free system integration. The RS422 port communications run at 9600 or 38400 baud, 8-bit
word, no parity, and 1 stop bit.

Configuration Options:

Sophia's MPC4-1530 comes in two configurations: a [system based] outdoor enclosure with
integrated cooling as shown above and a [module based] component housing (see component
SSPA data sheet). Additional options include: L-Band Block Up-Converter, and 28V and 48V DC
power supplies.

"We strive to offer the smallest size, lightest weight, and best value SSPA"
