5170-7125 MHz Bandpass Filter, 5 GHz and 6 GHz Wi-Fi

PRODUCT OVERVIEW This bandpass filter passes 5170 to 7125 MHz, a 1955 MHz wide passband. That covers 5 GHz Wi-Fi from channel 36 upward and the full 6 GHz band. Insertion loss is under 1 dB. Rejection across the 2.4 GHz ISM band is 40 dB. Harmonics are rejected too. The second harmonic of every frequency in the passband (10340-14250 MHz) is down 30 dB, and so is the third harmonic (15510-21375 MHz). Put it in front of a receiver, SDR, or spectrum analyzer to cut 2.4 GHz energy before it reaches the front end. Put it on the output of a low-power transmitter to reduce harmonics. The maximum input power is 3 W (+34.8 dBm). It connects with SMA-F connectors. APPLICATIONS 5 GHz and 6 GHz Wi-Fi. The passband covers channel 36 upward and the entire 6 GHz band used by Wi-Fi 6E and Wi-Fi 7. Use it for test benches, receiver front ends, and access point development. 2.4 GHz coexistence. With 40 dB of rejection across the 2.4 GHz ISM band, it protects a 5 GHz or 6 GHz receiver that shares a platform with Wi-Fi, Bluetooth, or other 2.4 GHz radios. Transmit harmonic filtering. It handles up to 3 W and rejects second and third harmonics by 30 dB. It fits on the output of low-power 5 GHz and 6 GHz transmitters, including 5.8 GHz FPV video and data links. Spectrum analyzer and SDR preselection. It keeps strong 2.4 GHz signals from overloading the input. This suits SDRs that tune up to 6 GHz. 5.8 GHz FPV video and unlicensed links. The 5725-5875 MHz ISM band and the common FPV video channels sit inside the passband. 5 cm amateur band. It covers 5650-5925 MHz for amateur microwave work. 5.9 GHz vehicle communications. DSRC and C-V2X operate at 5850-5925 MHz. Point-to-point microwave links. It suits fixed links in the 5.8 GHz and 6 GHz bands. System integration. The SMA connectors let you drop it inline between an antenna and a radio, LNA, or analyzer. SPECIFICATIONS Passband 5170-7125 MHz Bandwidth 1955 MHz Insertion loss Less than 1 dB Rejection, 2.4 GHz ISM band 40 dB Rejection, 10340-14250 MHz (2nd harmonic) 30 dB Rejection, 15510-21375 MHz (3rd harmonic) 30 dB Maximum input power 3 W (+34.8 dBm) Operating temperature -40 °C to +85 °C Connectors SMA-F x 2 or SMA-M + SMA-F Impedance 50 Ω Return loss 10-15 dB PLACEMENT TIP Insertion loss under 1 dB means the noise figure penalty ahead of an LNA is under 1 dB. For the lowest system noise figure, place the filter after the first LNA. Place it first when overload is the problem. RELATED PRODUCTS 5 GHz Filter
