The MX800 advanced design,
uses the latest component technology to achieve superior performance in high RF
environments. The sensitive receiver features a wide switching bandwidth and at the same
time, maintains good blocking, Intermodulation and adjacent channel performance.The
broadband transmitter exciter module has very low spurious emission levels, and is
followed by an efficient RF power amplifier. The optimized PA heatsink design results in
lower transmitter temperature rise during continuous operation.
Features
• Complementing the wide RF switching bandwidth (greater than 10 MHz in
all bands) the MX800 has an exceptional frequency coverage between 30 MHz and 960 MHz.
• An extended low frequency transmitter modulator response (DC to 3.4 kHz)
permits the use of the MX800 in paging and other data applications.
• An extremely fast transmitter rise time with controlled soft start
results in low transient emissions.
• Fast mute action, combined with fast TX, makes the MX800 suitable for
many trunking and data systems.
• Functionally independent TX and RX mean that crossbanding is easily
accomplished.
• A non-predictive CTCSS decoder will recognize any valid tone and
transmit a user associated TX tone.
• Continuously rated at full operating power, the MX800 has a thermally
controlled high MTBF fan ensuring cooler PA operation.
• Low current consumption on both TX and RX.
• 255 RF channel capability with operating channels optionally selectable
from rear inputs.
• An automatic PA protection circuit reduces the output power at high VSWR
and high temperature.
• Advanced fractional synthesizer design.
• Fully configurable by hardware and software for special applications.
Reliability
Reliability is designed into the MX800 and effective manufacturing quality
control carries this into the finished product. Rugged machined module housing
construction and extensive use of surface
mount technology provides outstanding reliability under the harshest
conditions.
Construction
The MX800 is a compact lightweight transceiver housed in a 2RU height (89 mm)
fully welded steel case. The unit conforms to the 19" rack mounting standard and an
optional slider rail kit can be fitted. The module construction has been designed for
international EMC/EMI rules compliance and all RF modules are individually screened.
User Interface
RF, analog and digital signal line accessibility at the rear panel means that
the MX800 is a versatile transceiver which can be used in systems configured to special
requirements. For trunking applications, special system control functions are included.
The base station is serially programmable on a
per channel basis using MXTOOLS programming software. This software utility
also permits remote monitoring, control and diagnostics of the MX800. Parameters such as
PTT, Mute/squelch,
Alarms, Digital I/O etc. can also be monitored or controlled independently in Real
time
measured analog parameters include: CTCSS decoded frequency, CTCSS encoded
frequency, Forward and Reflected RF power, PA temperature, RSSI, RX and TX VCO volts,
Discriminator output audio level and DC supply volts.
