Very Efficient Power
Amplifier (VEPA-10W)
Features:
• Frequency bands:1.40 to 1.60GHz, 1.70 to 1.85GHz,
1.70 to 2.40GHz, 1.99 to 2.50GHz, 2.20 to 2.70GHz,
4.40-5.00GHz
• Very efficient
• High linearity
• Adjustable gain
• Local - rotary switch
• Remote control
• 9-32V DC supply voltage
• Compact and lightweight
Benefits:
Cobham’s Very Efficient Power Amplifier (VEPA) series is
specifically designed for COFDM and other demanding
modulation schemes. However, they can also be used for non-
linear modulation schemes like FM.
This 31W P1dB power amplifier provides up to 10 watts of
COFDM power or 20 watts of FM power in a small economical
package. This linear Class A power amplifier provides a
maximum of 41dB of gain.

Features:
• Frequency bands: 300 to 450MHz, 1.00 to 2.5GHz, 3.00 to
3.50GHz and 3.40 to 3.70GHz
• Ultra linear or saturated operation
• RF ports are open and short protected
• Operating gain - 17dB typical
• Short circuit/over-voltage protection and reverse polarity
protection
• 12-30V DC power supply range
Benefits:
Bringing performance and reliability to microwave transmission
of digitally modulated signals (COFDM, QPSK and BPSK), this
amplifier minimises distortion, providing superior signal quality for
complex multi-carrier modulation while minimising the DC power
consumption. Optional small, fanned heat sink, automatic level
control of RF output, water resistant enclosure, type N or TNC RF
connectors (DB-9 for DC), and custom feed lines.
SOLAMP – Robust 5W
Amplifier
Features:
• In line standalone controller
• Or USB to RS232 converter
• Remote client for CryptoWizard
Benefits:
A discrete and comprehensive portable device, the Field
Controller removes the need to take a PC into the field.
It acts as a secure carriage mechanism for field management
of encryption data. The Field Controller can also act as a
remote agent for the Cobham CryptoWizard application when
pre-loaded with encryption keys.
FCON – Field ControllerVery Efficient Power
Amplifier (VEPA-2W)
Features:
• Frequency bands:1.40 to 1.60GHz, 1.70 to 1.85GHz, 1.70 to
2.40GHz, 1.99 to 2.50GHz, 2.20 to 2.70GHz, 4.40-5.00GHz
• Variable Efficiency with local switch or remote
logic signal
• High Efficiency Mode – V 2W out for 12W DC
in (Linear)
• High Linearity Mode – V 2W with 25 dB MER
• 9-32 V DC Supply Voltage
• Compact and lightweight
• Reversed polarity protected
Benefits:
Cobham’s Very Efficient Power Amplifier (VEPA) series is
specifically designed for COFDM and other demanding
modulation schemes. However, they can also be used for non-
linear modulation schemes like FM. An innovative protection
circuit switches off the input signal when it exceeds the value
corresponding to about 4W COFDM output power and it also
turns off the input signal when it detects excessive mismatch
conditions.
