DX2400L1 RF Deck Features
The DX2400L1 RF Amplifier incorporates a number of innovative and useful features:
•
Fully Automatic Band Switching: The DX-2400L1can be controlled (optional converter
may be required) with the transceivers band data through CAT style optically isolated
interface.
•
For older transceivers without band data, the DX-2400L can sample the incoming RF
drive and determine the proper band of operation under microprocessor supervision.
•
Four Position Antenna Switch with automatic memory for last antenna used for each
band.
•
Optically Isolated RS422 / RS485 remote interface allows operation up to 1500 feet away
through one or two twisted cable pair with optional PC adapter and software package or
optional remote control head.
•
Optically isolated remote on capability from trans12V Auxiliary jack.
•
ALC: Negative going from 0 to negative 10 Volts, adjustable. SWR-ALC foldback
protection.
•
SWR overprotection circuit. Over temperature warning and shutdown protection. Over
/under voltage lockout protection. Overdrive protection. Hardware failure protection
(combiner balance, PIN T/R failure)
•
Digital bargraph for Forward Power, Reflected Power and True (computed) SWR.
•
PTT or selectable Full Loop QSK Keying to interlock transceiver and amplifier.
•
Vacuum antenna relay as standard equipment. PIN diode T/R switch available as an
option.
•
FLASH Microprocessor allows field upgrades of amplifier firmware.
•
Separate low voltage control transformer for bias and microprocessor circuits reduces
power consumption in continuous standby mode and allows metering of transceiver when
in bypass mode.
•
Full optic isolation of all control functions (Key In, Key Out, PTT, Band Data, Remote
On) from transceiver as well as full optic isolation of computer /remote interface port.
•
2400W PEP total dissipation rating of RF power transistors means conservative design
with plenty of headroom
•
Low Pass Filters constructed with 12 gage coils and custom high power capacitors.
•
Oversize (30 lb) heat exchanger and 4 thermostatically controlled, ball bearing, variable
speed cooling fans mounted in push – pull configuration for redundancy.
