Wideband Dual High Power Amplifier

MPA221 is a dual amplifier especially designed to be a companion of the MTK952.
In a typical configuration, MTK952 generate the local carrier and also (in master mode) a reference signal in isofrequency that can be transported thru coax or fibre (i.e. with MFL) and used as source for MPA221 to create a remote RF transmission (single frequency areas).

MPA221 as a frequency meter to lock on source carrier and to set up properly all internal filtering.
Thanks to an integrated calibrated direction coupler, MPA221 is able to measure the real transmitted power and uses this feedback to proper set up the gain and protect in case of antenna failure.

Maximum output power is 2 watt on each of 2 separated output, or 1 watt per carrier on 1 output combined.
The units is designed with a low profile and all connectors in front of be easily integrated into plastic case for remote application.

FEATURES

Slave module with frequency meter for single frequency application
330 MHz Bandwidth
Quadruple in quadrature output stage for high rejection to intermodulation
Output power up to 2 Watt (/2W0 option) or 1 Watt with combined channels
2:1 power combiner integrated (software selectable)
SWR (Stationary Wave Ratio) sensing on antenna outputs with control loop to set power output
Remote Monitor/configuration thru Ethernet port
Compact profile with connector on front to be easily integrate on plastic cases for remote application
Dual DC INPUT: 10-28Vdc thru DB25 connector

features	Key Features of Net-Log Dedicated reliable multi-channel recording hardware. Easy to use Windows™ remote operation for playback, archiving, streaming and configuration. Independently configurable channel pairs to record at different sample rates, different bit rates and in mono or stereo. Recording duration configuration of the channels to suit your needs, e.g. 2 channels of low quality logging for 12 months together with two channels of high quality logging for 1 month, on one machine. Record inputs can be controlled remotely, e.g. snoop recording from mic-live output of a mixer. Automated voice recording – each channel can start and stop recording automatically by setting audio threshold levels, which means that it can be used for voice controlled systems and telephony recording. Up to 250, 000 recordings per channel can be made. Each Net-Log has its own IP address, so a number of machines can be installed on the same network. Fail-safe alarm indicators and remotes. Password protection and security access rights to system. Support for hard disk sizes up to 2048GB. Recordings can be made using optional G.729 algorithm, allowing longer recordings and lower network traffic. G.729 audio quality is comparable to MPEG L2 at 32kbits/sec when used to record/playback speech. Recording on Net-Log can be controlled serially by Crestron and Televic board room controllers.
