Best High Pass Radio Frequency Filters

Best Choice No. 1
Distill:FM Barebones – Broadcast FM Bandstop (Notch) Filter for Software Defined Radio (SDR) Applications
  • A high-quality, high-performance bandstop filter designed to attenuate broadcast FM for software defined radio (SDR) applications, with minimal interference to adjacent bands and tiny insertion loss. Bandstop design means the filter will pass DC (bias-t power)
  • Makes a great companion to any SDR, but especially RTL-SDRs like our NESDR series, which can be easily overloaded by strong broadcast FM signals
  • Distill:FM has its filter circuitry fully shielded with an EMI frame, and has its front end protected by an ESD diode meant for RF applications
  • Designed and manufactured by Nooelec in the United States. Full 2 year product warranty direct through Nooelec
Best Choice No. 2
Ancable in-Line High Pass Filter Coupler Barrel Adapter 54-1000MHZ 2-Pack
  • – These 54MHz high pass filter attenuate (remove) noise in the sub-band section of the cable spectrum. This filter can also be used to eliminate or restrict user access to the sub-band return frequencies.
  • – They are commonly used to remove unwanted noise on cable television caused by interference, or by cable installers to prevent access to unencrypted cable television channels using the lower frequencies
  • – Impedance 75Ω,Bandwidth 54-1000MHz,Return Loss 16dB, Insertion Loss 1.5dB
  • – F type male to female
  • – Package include: 2PCS connector
Best Choice No. 3
Flamingo AM – Broadcast AM Bandstop Filter (AM Notch Filter) for Software Defined Radio (SDR) Applications
  • A high-quality, high-performance broadcast AM bandstop filter designed for software defined radio (SDR) applications. Includes free male SMA-male SMA barrel connector! Designed and manufactured by NooElec in North America. Impeccable quality and full 2-year warranty
  • Broadcast AM stations can be particularly problematic due to the high-powered transmitters used for broadcasting in some areas. These signals can overload the front end of an SDR, causing imaging and a number of other issues. As such, Flamingo AM makes a great companion to our Ham It Up series of HF upconverters (available separately on Amazon)
  • Flamingo AM was designed to provide approximately 40dB attenuation for broadcast AM frequencies, while ensuring that adjacent bands are minimally affected. The -3dB rolloff of the filter is 350kHz and 1900kHz. The minuscule out-of-band insertion losses means the filter can stay in place for most any application–though we do recommend removing Flamingo AM from the signal chain when not receiving HF frequencies
  • Flamingo AM is a proper bandstop filter, so you are able to pass-through DC (bias-tee) power when required. DC current handling is 250mA (min), and the maximum recommended signal level is 18dBm (5Vp-p), so there is no issue using the filter for higher-power applications
  • The filter is fully EMI shielded, installed in a custom anodized aluminum enclosure for further protection and isolation. The front end is protected by an RF-rated ESD diode, which provides protection not just for your filter, but also the radio or SDR behind it
Best Choice No. 4

  • Convenient debugging, good selectivity and stability
  • The filter has the characteristics of low insertion loss, high resistance band rejection and high image attenuation, high power tolerance, low cost and miniaturization.
  • A band-pass filter is a device that allows a particular frequency band to block other frequencies simultaneously.
  • With high reliability, stable and reliable working performance
  • 100% brand new and high quality
Best Choice No. 6
Harrison Labs FMOD Inline Rumble Subsonic Filter Crossover Pr 30Hz High Pass RCA
  • 12dB/Octave slope
  • 24kt gold over brass construction
  • 10 volts maximum RMS input
  • One-year manufacturer warranty
  • Made in the U.S.A
Best Choice No. 7
433MHZ Low-Pass Filter LPF RF HF Radio Lowpass 7th-Order Elliptic Function 470M
  • A low-pass filter passes signals below the cutoff frequency, while signals above the cutoff frequency are attenuated.
  • Commonly used for the suppression of high-order harmonics of electromagnetic signals, or placed at the back of the mixer to filter out high-frequency clutter, which plays the role of frequency selection.
  • This filter can greatly attenuate signals above 470M, and its harmonic suppression capability is about 50dbc.
  • Compared with several low-pass filters, the elliptic filter can obtain a narrower transition bandwidth and a smaller bandwidth than other types of filters such as Butterworth and Chebyshev filters under the same order.
  • The filtering steepness is better than filters of other properties.
