Draft Salient Specifications

For

MICROWAVE TUNERS – QTY 28 Channels Req.

Category Sub-Category Parameter Value Units Notes General See Notes See notes Rackmountable 4-channel microwave tuner system. Each channel accepts an RF input and provides dual analog IF outputs (tuned to same RF frequency):

1 GHz center with 500 MHz IF Bandwidth, 160 MHz with 80 MHz IF Bandwidth. The term "system" does not necessary mandate a single chassis solution.

Format and Packaging

Turn-Key See Notes See notes The government requires a turn-key chassis-level solution, mostly independent of underlying tuner platform/technology.

Quotes/bids shall address obsolescence and/or support over 20+ years: this renders VME-based solutions as undesirable. Regardless of technology platform, turn-key solution and bid will include all necessary subsystems (e.g., single-board computer, Ethernet switch, rackmountable chassis, internal cables, etc.).

Modularity See Notes See notes The government is requiring at least 4 independent tuning channels (where a "channel" consists of an RF input and dual IF outputs) within the physical space constraints specified below. Additionally, tuner channels shall be modular with a granularity of two tuner channels maximum. That is, tuner channels shall be field-replaceable at one-channel or, at most, two-channels at a time. Single-channel granularity is preferred unless dual-channel allows significant cost reductions. Vendors may provide quotes for both single- and dual-channel granularity solutions if so desired. Note that each tuner-channel in a "dual-channel granularity" system shall be able to be tuned independently.

See Notes See Notes Required number of chassis and configuration shall be in accordance with the included "Chassis Configuration", depending on proposed modularity

Hardware-Based Tuning

See notes Users shall be able to control the tune frequency through an external hardware (HW) strobe/trigger (in addition to the SW interface). While HW-controlled, the tuners shall be able to step through a predefined "tuner table" upon every receipt of a strobe. Via the SW interface, users shall be able to create a "tune table" of at least 256 entries. Each entry shall include center tuner frequency, RF attenuation and IF attenuation values.
