- This synopsis is being posted to both the Federal Business Opportunities (FBO) page located at http://www.eps.gov and the Navy Electronic Commerce Online (NECO) site located at http://www.neco.navy.mil. While it is understood the FBO is the single point of entry for posting of synopsis and solicitations to the internet, NECO is the alternative in case FBO is unavailable. Please feel free to use either site to access information posted by the Naval Sea Systems Command. Synopsis N00178-06-R-1911 is being issued to modify N00178-06-C-1031. This modification is to include an additional quantity of 1 each, Model RDB-2000 Dual Channel Telemetry Receiver, available from L3 Communications Microdyne, located at 1515 Grundys Lane, Bristol, PA 19007-1506 under Contract N00178-06-C-1031. CLIN 0002 - One (1) each, Model RCB-2000 Dual Channel Telemetry Receiver. The dual channel receiver/combiner (DCRC) unit will be used for the reception, pre-detection combining, demodulation and bit synchronization of U.S. Navy telemetry data in the 2185 Mhz to 2485 Mhz frequency spectrum. The DCRC shall be capable of receiving two independent RF streams and pre-detection combining them into a single intermediate frequency (IF) output. The DCRC shall provide the capability to take the combined IF output and demodulate it into a video stream output. Several modes of demodulation shall be supported including frequency modulation (FM), phase modulation (PM), bi-phase shift keying (BPSK) and Quadrature phase shift keying (QPSK). The DCRC shall support modulated signals with data rates from 5 samples per seconds to 20 Mega samples per second in all modes. Setup and control of all DCRC functions shall be supported through front panel controls and remotely via RS-232C, IEEE-488 and 10 base T ethernet connections. The RCP shall conform to all IRIG 106-96 telemetry standards. RECEIVER REQUIIREMENTS- Each of the 2 receiver channels shall meet the following minimum requirements: a) Receiver Type: Shall be superheterodyne conversion; b) RF Frequency Range: Shall be tuneable from 2185 to 2485 Mhz in 0.1 Mhz steps; c) Noise Figure: Shall be12 dB Maximum; d) Input Impedance: Shall be 50 ohms plus or minus 3 ohms; e) Input VSWR: Shall be 2 to 1 maximum; f) Image Rejection: Shall be 55 dB minimum; g) IF Rejection: Shall be 55 dB minimum; h) Spurious Rejection: Shall be 45 dB minimum; i) Dynamic Range: Shall be threshold to plus 10 dBm; j) First Local Oscillator Characteristics: Shall be synthesized with 100 Khz tuning increments; k) Second Intermediate Frequency (IF) : Shall be 70 Mhz plus or minus 1.5 parts per million; l) Second IF Filter Bandwidths: Each receiver channel shall include the following IF filter bandwidths centered at 70 Mhz with each filter having a symmetry of plus or minus 10 percent: 300 Khz, 500 Khz, 750 Khz, 1 Mhz, 1.5! Mhz, 2.4 Mhz, 3 Mhz, 3.3 Mhz, 4 Mhz, 6 Mhz, 10 Mhz, 15 Mhz, 20 Mhz; m) Automatic Gain Control (AGC) Characteristics: Each receiver channel shall provide an AGC output which is linear to plus or minus 2 dB over any 30 dB range. AGC time constants of 0.1, 1 10, 100 and 1000 milliseconds shall be provided; n) Amplitude Modulation (AM) Detection Characteristics: Each receiver channel shall provide an AM output with a frequency response up to 50 Khz; o) Outputs: The following rear panel outputs shall be provided from each receiver channel as a minimum; 70 Mhz 2nd IF output, AGC output, AM output; p) Control/Status: The following parameters shall be controllable via front panel controls and/or all remote interfaces for each receiver channel: RF frequency, IF Bandwidth, AGC Time Constant, AGC Signal Level, AGC Zero/Scaling. PRE-DETECTION COMBINER MODULE REQUIREMENTS. The combiner module shall accept AGC and 70 Mhz 2nd IF inputs from both receiver modules and generate a composite output signal in 1 of 4 modes: optimum ratio combining, optimum selection combining, channel 1 only and channel 2 only. In optimum ratio mode, the combiner shall sum the signals from each receiver channel in a weighted fashion based on relative AGC signal levels up to gain a maximum signal to noise ratio improvement of 2.5 dB when the signal inputs from each receiver are equal. In optimum selection mode, the combiner shall select the receiver channel which has the highest AGC signal level and pass it through as the combined signal. In channel 1 and channel 2 only modes, the combiner shall only pass through data to the combined output from the selected received channel. The combiner mode shall be controllable via front panel controls and/or all remote interfaces. MULTI-MODE DEMODULATOR REQUIREMENTS. The multi-mode demodulator shall accept the combined pre-detection signal output, demodulate the signal and provide a baseband video output. The unit shall support demodulation of the following modes: FM, BPSK and QPSK. The FM demodulator shall include trellis demodulation technology. The multi-mode demodulator shall also meet the following additional requirements: a) Acquisition and Tracking: The demodulator shall have and acquisition and tracking range of plus or minus 250 Khz in all modes; b) Linearity: The demodulator shall have a maximum distortion and linearity of 5 percent in all modes; c) Video Output: A rear panel video output with 75 ohms impedance shall be provided. Video output voltage shall be user selectable with a maximum output of 8 volts peak to peak, Video output coupling shall be user selectable AC or DC; d) Video Filters: Selectable low pass filters shall be provided for the demodulated video outputs.
