DAB Power Amplifier 174-230 MHz; Dual Power Supply

It features a state-of-the-art LDMOS solid-state output that can provide up to 30W (average) or 50W (peak) composite RF output power in single carrier applications. For Multiple Carrier Power Amplifier (MCPA) applications, such as multi-channel DAB/DAB+ rebroadcast systems, the excellent linearity of this amplifier optimises the number of RF carriers and their individual RF output powers that can be provided - subject to the allowable Intermodulation Products (IM) performance. This full-featured, high performance RF power amplifier is compatible with narrowband and wideband modulation schemes and is self-contained with redundant dual-PSU (a standard single PSU model is also available) and high-volume fan cooling system. Dual front panel digital displays indicated RF Fwd and Rev composite output powers. Dry relay alarm contacts are provided for connection to external monitoring equipment if desired. The unit (DAB Power Amplifier 174-230 MHz) is housed in a compact 3RU 19-inch rack mount enclosure for convenient installation and maintenance.

• 30W (average) 50W (peak) single carrier or Multiple Carrier Power Amplifier (MCPA) operation
• High-linearity, "State of the Art" LDMOS design.
• Integral isolator protects the amplifier from output mismatches.
• Dual front panel digital displays (RF Fwd and Rev Pwr)
• Integral fan cooling system
• Alarm monitoring via voltage free contacts
• Space-efficient 3RU 19in rack mount enclosure

Note 1. The number of RF carriers and the per-carrier RF Output power capability in multiple carrier (MCPA) applications is subject to the allowable resulting Intermodulation Products (IM) and RF Spurious Suppression performance.
