59 -- REMOTELY CONTROLLED HIGH FREQUENCY TRANSMITTING COAXIAL SWITCHING SYSTEM AND COAXIAL MATRIX SWITCH CONTROLLERS SOL DTCG23-95-R-TAU021 DUE 091195 POC Connie E. Mease, Contract Specialist, 202-267-2502; Jerome S. Hensley, Contracting Officer, 202-267-6211 This specifies the requirements for a Remotely Controlled High Frequency Transmitting Coaxial Switching System and Coaxial Matrix Switch Controllers. Physical/Electrical Requirements: Operating Temperature: 0 - 40 Degrees C; Operating Humidity: 0 - 95 percent non-condensing; Primary Power: 120 VAC +/- 10 percent, 50/60 Hz +/- 5 percent Single Phase; Frequency Range: DC to 32 MHz; Impedance: 50 Ohm Coaxial; Insertion VSWR: 1.10 Maximum; Insertion Loss: .3 dB Maximum for the proposed switch; Power Rating @ 32 MHz: 30 KW average, 100 KW PEP @ unity VSWR; Cross Channel Isolation: 70 dB Minimum @ 32 MHz; RF Terminations: 1-5/8'' EIA Male Flange; Switch Activation Time: (.7 sec. after enable command; Leakage Current: NTE 5 Milliamperes; Cross Point antenna grounding capability; Cross Point Keyed Lockout System; Weight (Maximum): Not greater than 400 lbs. per sq. ft. (Maximum) displacement. Installation of the matrix switch and controllers at U. S. Coast Guard Communications Station, Chesapeake, VA is required. Space in the control room where the matrix system will be installed is limited. Operator physical access to all switches shall be from the front of the matrix for quick and easy operator access during a power loss at the matrix. Equipment offered must be capable of accepting command control information from a Coast Guard Standard Workstation (CGSW) computer running Coast Guard developed antenna matrix control software. Copies of the control software will be available to interested sources. The Coast Guard will not lend or let be used Coast Guard CTOS/BTOS equipment for purposes of verification. The Coast Guard will not purchase or accept billing of computer equipment as part of offer. Sources that responded to the previous sources sought notice and notice of intent synopsis dated April 6, 1994 and May 31, 1994 respectively, need not respond again. A copy of the solicitation will be provided. Other sources interested must submit their written request within 15 calendar days of publication of this announcement.
