Anatech Electronics, Inc. RF Multiplexers AM1900D325

The AM1900D325 is a ceramic duplexer designed for RF applications, operating within two frequency bands: 1920-1980 MHz and 2110-2170 MHz. Each band features a bandwidth of 60 MHz, with a minimum passband return loss of 10.5 dB. The insertion loss is specified at a maximum of 1.5 dB for Band 1 and 2.0 dB for Band 2, while passband ripple is limited to 0.5 dB and 0.6 dB respectively. The device offers isolation of at least 51 dB for Band 1 and 46 dB for Band 2, with a maximum power handling capability of 2 W. The duplexer has a 50 Ohm input/output impedance and is suitable for surface mount technology (SMT) with dimensions of 9.93 x 5.45 x 1.90 mm. It operates effectively in a temperature range from -40 to +70 degrees Celsius and can be stored at temperatures between -50 to +90 degrees Celsius. Additionally, the product is RoHS compliant, making it suitable for environmentally conscious designs.
