I. GENERAL & ELECTRICAL REQUIREMENTS
1. Center Frequency (FON): 70.2MHz
2. 3dB Passband:
@ 25C ± 2C:  FON 6.0kHz & ≤ FON 9.0kHz
-30C to +75C: ≤ FON 5.5kHz & ≤ FON 10.0kHz
3. Insertion Loss (@ peak of transmission within the 3dB passband): ≤ 4.0dB
4. Passband Ripple (peak-valley, FON 3.5kHz): ≤ 0.5dB
5. Coupling Capacitance: T.B.D. (Vendor to Advise After Prototype Build)
6. Group Delay Distortion (peak-peak over FON 3.0kHz)
@ 25C ± 2C: ≤ 20µsec
-30C to +75C: ≤ 30µsec
The group delay distortion value shall be the difference between the
maximum and minimum values over the specified frequency range.
7. Rejection (Minimum, Relative to Insertion Loss):
35dB: FON 25kHz to FON 500kHz
80dB: FON -910kHz
8. 3rd Order Input Intercept Point (IIP3):+26dBm
The IIP3 shall be first tested with tones at fc -50kHz and -100kHz
and then tested with tones at fc +50 kHz and +100kHz, , the tone level shall be -20dBm/tone at the filter input.
9. Input Signal Level: ≤ 0dBm
10. ZIN/ZOUT: T.B.D. (Ω // pF) nominal (Vendor to Advise After Prototype Build)
Note 1: All electrical performance specifications, unless otherwise noted, are over the full operating temperature range.
Note 2: All performance parameters are to be validated at the prototype build stage and are subject to adjustment.
II. ENVIRONMENTAL & PHYSICAL REQUIREMENTS:
1. Temperature Range
Operating: -30C to +75C
Storage: -40C to +85C
2. Solderability: Per EIAJ-STD-002
3. Package: 5x7mm Matched Pair Tandem Set SMD (ref drawing Figure 1)
4. Full RoHS Compliance
