RF放大器

The 1020L Amplifier is a rugged source of RF
power for ultrasonics, induction heating and
laser modulation as well as plasma applications.
It is a totally solid state solution employing RF
DMoS FETs in the power amplification stages,
offering simultaneous forward and reverse
power readouts, and RS232 port for data
collection. The 1020L reflects E&I’s commitment
to reliable and robust RF power.

Protection:
INPUT: unit will withstand up to +13dBm input
without damage.
THERMAL: the unit can operate at 45OC
ambient. If the internal temperature becomes
too high the unit will shut down and an error
message will appear on the front panel. The unit
may be re-set by cycling the power or from the
RS232 input.
MISMATCH: the unit will tolerate any mismatch
subject to thermal and current protection.

The 1020L produces 200 Watts of quasi linear
class AB power over a frequency range of 10
KHz to 5 MHz, with a nominal power gain of 53
dB (+/-1dB). Operation over the entire frequency
range is possible without the need for any
switching.
The front panel display provides simultaneous
measurements of forward and reflected power
as well as the unit’s status. The RS232
connector at the rear of the unit can also be
used to capture this data and reset the unit
should a fault occur.
The E&I 1020L is a 19” rack mount unit 3U high.
It employs an integral power supply capable of
operation at 115 or 220 VAC, 50 – 60 Hz. The
unit weighs approximately 45 lbs or 16 Kg.
