LPF HF +50MHz for 100W SSPA RD70HHF1 RD100HHF1, Low Pass Filter
LPF HF +50MHz for 100W SSPA RD70HHF1 RD100HHF1, Low Pass Filter. This product data sheet is originally written in English.
This is a 7th order Chebyshev Low Pass Filter for using after HF power amplifier for removing harmonic. This LPF intended for HF amateur bands - 1.8 MHz, 3.5 MHz, 7.0 MHz, 10 MHz, 14 MHz, 18 MHz, 21 MHz, 24 MHz, 28 MHz and 50MHz. 3dB cut off frequency is 2.5 MHz, 5 MHz, 8.6 MHz, 15.5 MHz, 25 MHz, 35 MHz and 55 MHz.
You can choose cut off frequency by setting up binary code with 3.3v or 5v logic levels (onboard jumper selectable), see pictures above. 1.8MHz-28MHz insertion loss is about 0.5 dB or less. 50 MHz band insertion loss is 0.8dB.
You can see attached graths for exact, per bands, values. Input and output impedance is 50 Ohm. Input and output connectors is SMA female.
LPF Return Loss is better than 30 dB for 1.8MHz-28MHz and 28dB for 50 MHz. Maximum handled power for any band is 100w. With 50% duty cycle with no external cooling, 100% duty cycle with air colling. Only high quality and original components using - AMIDON T68 and T50 cores, and NP0 Hi-Q, low ESR RF capacitors. Temperature should be under control. Board size is 149 x 110 mm. Power supply - 12v 0.2A max. This item is in the category "Mobile Phones & Communication\Radio Communication Equipment\Ham/Amateur Radio\Ham Radio Amplifiers".
