5HT-40020AS-400 – TOKO

The 5HT-40020AS-400, manufactured by TOKO, is a discrete bandpass filter centered at 400 MHz. This surface-mount device (SMD) utilizes a multi-pole LC network to achieve a specified passband insertion loss, typically less than 3 dB within a defined bandwidth. The filter exhibits a characteristic impedance of 50 ohms, facilitating integration into standard RF signal chains. Attenuation outside the passband is a critical parameter, with typical values exceeding 20 dB at frequencies ±50 MHz from the center frequency. The 5HT-40020AS-400 is designed for applications requiring precise signal selection and rejection of unwanted frequencies, such as wireless communication systems, instrumentation, and radar receivers operating near 400 MHz. Performance characteristics, including insertion loss, return loss, and group delay, are typically specified over a temperature range of -40°C to +85°C.
