Specification for a Lowpass LC Filter
MtronPTI P/N: LF9687
I. General & Electrical Requirements
1. Cut off Frequency : 975MHz
2. Insertion Loss (175MHz to 975MHz): ≤ 2.0dB
3. Passband Ripple (175MHz to 975MHz, peak‐peak): ≤ 0.5dB
4. Input Return Loss (across the pass band) : 15dB minimum
5. Output Return Loss (across the pass band) : 15dB minimum
6. Max Input power : +10dBm
7. Stopband Rejection (1275MHz to 3000MHz):60dBc minimum
8. ZS/ZL: 50Ω ±10%
II. Environmental & Physical Requirements:
1. Temperature Range:
Operating: ‐40˚C to +85˚C
Storage: ‐55˚C to +110˚C
2. Temperature shock:
Operational: Unit shall be capable of operation when exposed to temperature shock of minimum of 5 degrees
C/ Min over the operating temperature
Non‐operational: Units shall survive without damage in non‐operating condition after repeated exposure to a
temperature shock of 10 degrees C/ Min over in the storage temperature range.
3. Vibration:
3a. Unit shall be capable of full performance when exposed to the vibration conditions listed in Table 1.
