This is a Questions and Answers document addressing clarification on filter specifications for a federal contract solicitation. A contractor inquired about missing stopband specifications (frequency and attenuation requirements) that were essential for obtaining manufacturer quotations. The government responded that the stopband frequencies were contained in the original requirements document and provided complete technical specifications for six filters.

The solicitation requires six RF filters with the following specifications: Filter 1 (2200-2400 MHz, band-pass), Filter 2 (2600-3700 MHz, band-stop), Filter 3 (350-450 MHz, band-pass), Filter 4 (5300-6000 MHz, band-stop), Filter 5 (5600-5700 MHz, band-pass), and Filter 6 (1400-1900 MHz, band-pass). All filters must meet uniform performance requirements: attenuation ≥30 dB, SMA female-to-SMA female connectors, power handling ≥1 W, VSWR ≤1.5:1, and passband ripple ≤1 dB. Size constraints are not specified, with preference for smaller units. The response clarifies that the frequency and attenuation data were available in the original solicitation materials, specifically in the 2nd and 3rd line items of each filter requirement section.
