Single-Sideband Filter Crystal Filter SSB CW Filter Description
1. The single-sideband filter is made with a 9 MHz crystal and is of the Cohn type. The Cohn-type filter is also a single-sideband circuit with a simple and practical effect.
2. The manufacture of single-sideband circuits is a very critical part. The parameters of crystals from different manufacturers and batches vary greatly. Manufacturing a filter based on theoretical calculations is generally not very useful, which is also a major reason for the failure of many manufacturers in circuit production.
3. For a high-resolution scalar or vector network, fabrication is generally simpler under theoretical conditions, but also requires many experiments and several parameter corrections. However, even if this is achieved with the aid of the instrument, the effect is still guaranteed. The parameters of this 9M state z are as follows: a. The center frequency is approximately 8.998 MHz; b. The bandwidth of -6 dB is approximately 2.3 kHz; c. The center frequency loss is approximately -4.73 dB; d. The attenuation ratio is close to 100 dB; c. e. The filter uses an LC impedance matching circuit to bring the impedance of both ends to 50 ohms. Without the LC circuit, the impedance at both ends is approximately 120 ohms. Color: Green. Material: ABS. Package includes: 1 x Single-Sideband Filter. Only the above-mentioned package contents are included; other products are not included. Note: Light reflections and different displays may cause the color of the item in the picture to differ slightly from the actual product. The permissible measurement error is +/- 1-3 cm. [OnBuy.com]
