MAXIMUM RATING: 1.Input Power Level: 15 dBm 2.DC voltage: 3 V RoHS Compliant Lead free Lead-free soldering 3.Operating Temperature: -40°C to 85°C 4.Storage Temperature: -40°C to +85°C B. ELECTRICAL CHARACTERISTICS: Item Unit Min. Typical Max. MH - 408 - Minimum Insertion loss 406 ~ 409 MHz ILmin dB - 1.6 2.5 Passband Ripple 406 ~ 409 MHz dB - 0.3 1.8 MHz 3 8 - Center frequency Fc 3dB Bandwidth BW-3dB Attenuation (Reference level from ILmin dB) 358.5 MHz dB 40 72 - 358.5~384.0 MHz dB 35 62 - 400.0 MHz dB 10 34 - 415.0~423.0 MHz dB 5 21 - 423.0~503.0 MHz dB 40 50 - ppm/k - -37 - Temperature coefficient of frequency Source impedance Zs Ω - 50 - Load impedance ZL Ω - 50 - Note1: ILmin is the minimum of the pass band attenuation. The center frequency Fc is the mean value of the upper and lower frequencies at the 3dB filter attenuation level relative to the ILmin. Note2: The room temperature, Tr, is 25° C. FTC is temperature coefficient of frequency. The nominal frequency at temperature, Tc, may be calculated from f= Fc [1-FTC(Tr-Tc)]. C.
