Common modularity
Transceivers and transmitters basically differ in some modules only
|
Reduced costs
|
Continuous operation
- Convection cooling
- Generously dimensioned heat sink
- Gradual power degradation in case of adverse operating conditions
- Automatic switching off at critical temperature
|
High communication link reliability |
| Rear heat sink |
Cost-effective installation in standard racks
- L-shape plug-in slide rails are sufficient
- No need for telescopic rails
|
| Variety of PTT (push-to-talk) and squelch techniques
|
High system flexibility
- Interface adaptable without problems
- Easy to test
|
Excellent spectral purity
- Low-noise synthesizer
- Careful design of power amplifier etc (minimizing non-linearity product emission)
- Harmonics filter
- R&S® GD200V VHF or R&S® GD200U UHF circulator set (option) provided for insertion in front of harmonics filter (maximum efficiency) to improve TX intermodulation characteristics
|
Interference-free operation
even under co-site conditions
|
Transceivers include 2 synthesizers
- Receive synthesizer in RX unit
- Transmit synthesizer
|
Half-duplex and full-duplex concepts
(relay stations) configurable
|
Automatic frequency offset
of transmit synthesizer in case of reception.
This concept prevents permanent synthesizer on/off switching following the TX/RX mode
and thus prevents the generation of unwanted spurious frequencies
|
High-quality reception
in TX/RX mode
|
Alternative VHF TX synthesizer models
- R&S® GF201V model .24 with TCXO:
This VHF model is fitted with the required stability, with 2.5 kHz frequency setting steps
and with user-selectable channel spacing of 25 kHz and 8.33 kHz
- R&S® GF201V model .25 with OCXO of extreme stability
|
Same benefits as before
Standard transceiver models "all-in-one"
- For standard operation or
- For 2-, 3-, 4-carrier offset transmissions (with 25 kHz spacing)
- For future 8.33 kHz mode: no need for expensive change of TX synthesizer
- For single- and multichannel operation, thus reduced logistics effort High-precision transceiver models for special applications
|
Alternative UHF TX synthesizer models
- R&S® GF201U model .22: This standard model includes a TCXO
- R&S® GF201U model .23: This model is fitted with an OCXO
|
Same benefits as before
|
Alternative power amplifier models and use of 2nd RF socket for RX antenna
- With highly reliable TX/RX PIN diode switch
- Without TX/RX PIN diode switch
<%br>
The 2nd RF socket is wired for the RX antenna
|
Interference-free co-site operation
- One-antenna transceiver model for standard standalone applications
- Two-antenna mode available for separate transmit and receive antennas to master co-site environment
- High MTBF (no mechanical coaxial TX/RX relay)
|
Designed as 19" 3 HU plug-in unit
- Internally and externally loaded modules
- No motherboard
- Space for future customer-specific options
- Swivel-type design of rear power amplifier module for ideal accessibility in the event of tests during full operation; heat sink and flexible cabling remain connected
|
Economical and future-proof design
Excellent serviceability
- No external connection of two separate (TX + RX) units
|
| Clearly arranged control and monitoring elements on front panel
|
Helpful service functions for fast status checks |
