Highpass Filter (Sample Graph, HP7 Customizing, Order Info)

Custom modify and enhance your HP7

HP7-536/557, Highpass is used to isolate UHF ch.28 and above from ch.24 and below. Sample Graph illustrates custom required specifications including:

Operating Bandwidth: Fc to 750 (optional: 550 / 750/ 860 / 1000 MHzl)
Cut off Frequency (Fc): e.g., 557 MHz
Stopband Frequency (Fs): e.g, 536 MHz
Transition: e.g., Fs / Fc = 1.04 approx (4 %), Specify transition with Fc and Fs in MHz.
Stopband: e.g., > 40 dB at Fs (536 MHz) Available attenuation: 15 to 70 dB
Passband Loss: < 1.5dB, except at cut-off Fc
Flatness: ±.5 dB (flatness depends on transition)
Return Loss: e.g., : >16 dB, (VSWR: 1.35 : 1)
Impedance: 75 ohms (50 ohms - optional)
Connectors: 75 ohms, F-type (F). Optional: 75 ohms F-type (M) and BNC, and, 50 ohms BNC / N / sma
Power pass: Non (optional 2 A max)
Housing: Indoor or Outdoor
Standard Dimensions (in): 3.6L x 1.5H x 3.2W

Order information

Order as:

HP7-ch.( Fs / Fc ) - indoor
HP7X -ch.( Fs / Fc ) - outdoor

Specify:

Fc: Cut-off (channel or frequency). Fs (in MHz ) = Fc (freq) x .95 ( stopband

Ex: HP7-536/557 ( or HP7-ch. 80/86 )
Fc = 557, Fs is 557 x .95 = 537 MHz (approx)
