The 1С-475Н RF amplifier uses a low noise figure, high gain,
disk-type GaAs-FET (3SK129) for UHF applications. Also, high
sensitivity and a very high dynamic range are ensured since it uses
a balanced-type mixer in the mixer stage. This mixer incorporates
a UHF applicable transistor (25С2026) with 2GHz frequency
characteristics.
The 1С-475Н5 compact size - only 241mm(9.5")(W) x 95mm
(3.7")(Н) x 239mm(9.4") (D) - simplifies installation in most mobile
and portable situations: in automobiles, airplanes, boats or even in
suitcases.
The rear panel of the 1C-475H has ап easy-to-access terminal socket
for AFSK (Audio Frequency Shift Keying) operation. Use the
[DATA] SWITCH to rapidly switch between receive and transmit
operations. This convenient function is made possible in the
1С-475Н by ІСОМ" exclusive new DDS (Direct Digital Synthesizer)
System.
For CW operators, both semi break-in and full break-in are provided
for smooth, fast, and natural CW conversations.
Provides you with interference-free communications.
