The DRT2311C is a compact Wideband N-Channel Transceiver platform for third generation DRT hardware modules. The DRT2311C provides the same functionality as the DRT2301C, but the DRT2311C I/O connectors are located on the rear of the chassis adding 1U of height. In addition, the modules are recessed behind a removable panel which contains an air filter.
The DRT2312C is a DC powered-version of the DRT2311C. It has the same features and accessories, but DC power input replaces AC power input. The AC/DC adapter is included.
- Customizable transceiver module configurations with up to sixteen digital transceivers (eighteen analog transceivers) for up to 32 RF Channels (36 Analog RF Channels).
- Flexible tuner configuration provides frequency coverage of all bands of interest.
- RFT3A-40: Dual channel transceiver VHF/UHF coverage from 20-3000 MHz; HF coverage from
0.5 – 32 MHz usable (1.7 MHz – 30 MHz full spec coverage)
- RFT4: Dual channel transceiver VHF/UHF coverage from 20-6500 MHz; HF coverage from 0.5 – 32 MHz usable (1.7 MHz – 30 MHz full spec coverage)
- HFT1B: High performance HF receiver from 0.2 - 32 MHz (usable) (Future)
- System architecture allows blocks of simultaneous groupings of coherent and independent RF channels, all software-reconfigurable. Channel groupings are restricted to blocks within a given module and by adjoining slots.
- Fast-scan step control via rear panel sync connector, front panel sync connectors and/or time of day.
- Utilizes DRT’s third generation reference module (REF3-40). The REF3-40 provides:
- 10 MHz I/O and 1PPS I/O.
- Improved system phase noise relative to previous generation of DRT reference modules.
- BIT/CAL source, 0.5 to 3000 MHz, with programmable modulation.
- Built-in ovenized precision low-noise time base.
- Commercial GPS receiver allows reference generator to be locked to GPS via external antenna or 1PPS signal fed by another GPS receiver. Can also generate a 1PPS signal for synchronization with other modules and systems.
- Two slots (18 and 19) available for DRT’s second generation of Output Formatter Modules (OFM2):
- Allows for various transport mechanisms based on implementation requirements.
- First offering is DRT’s fiber optic OFM2.
- DRT’s fiber optic OFM2 provides half-duplex transmission/reception of a single RF channel over a single fiber optic link.
- Provides fiber optic transceivers for interfacing a maximum of 32 RF channels (16 RF channels per OFM2) to external hardware.
- Non-blocking switch backplane architecture allows for routing of any RF channel to any external fiber optic output and any external fiber optic input to any RF channel.
- The OFM2 optical transceiver transmits and receives data using the VITA 49 transport layer protocol, and VITA 17.2 link layer protocol (SFPDP) at a rate of 3.125 Gbps. Transport protocol allows the embedding signal related information with data (e.g., gain, frequency, time of day).
- The physical transport devices use a four-channel, 850 nm Vertical Cavity Surface Emitting Laser (VCSEL) transceiver conforming to the POP4 MSA (Four Channel Pluggable Optical Transceiver
Multi-Source Agreement). The optical interface accepts industry standard MTPTM(MPO) optical connectors. Example mating optical interface mating connector: Molex 86081-3030 MTP multimode connector, 50/125uM ferrule hole size.
- Fiber run lengths up to 400 ft. will be supported with 500 MHz.km fiber.
- Gigabit Ethernet control interface (TCP/IP).
- 3U CompactPCI technology.
