RF diplexers provide an efficient and convenient way of combining two different frequency signals or splitting a single frequency signal into two different frequency signals. The CER0286A is a one-port, band-selective, RF diplexer based on a stepped impedance AM bandpass filter. It has a wide usable frequency range from 1.7GHz to 2.7GHz, and a typical passband insertion loss of 3.0dB. This makes the CER0286A an ideal choice for applications like Wi-Fi, WiMax and cellular base stations.

The CER0286A is based on a stepped impedance AM bandpass filter which combines two separate AM signals in one port. It has two passbands, one in the range of 1.7GHz to 2.2GHz, and the other in the range of 2.4GHz to 2.7GHz. The filter can be tuned to reject or attenuate the other band’s signals while passing the desired one. This helps to reduce distortion and interference caused by mixing the two frequencies.

The CER0286A features a CompactRIO architecture, allowing users to quickly configure, monitor and control their system. It includes gain control and temperature compensation circuitry, as well as two independent, adjustable, voltage-controlled attenuators (VCAs) for setting the attenuation on each of the two bands. Its adjustable gain and signal level control make it suitable for a variety of systems, from traditional Wi-Fi to 3G networks.

When compared to similar devices, the CER0286A offers greater performance, allowing for a stronger signal-to-noise ratio. It has a small form factor which is ideal for space restricted systems, and is highly efficient at low power consumption. Additionally, the CER0286A has an easy-to-use web interface that makes it simple to configure, monitor and control the device.

The working principle of the CER0286A diplexer is based on the same stepped-impedance, AM bandpass filter used in the CER0285A. It features two separately tuned passbands, each with a different band-stop frequency that can be easily adjusted using the web-based interface. The device also includes voltage controlled attenuators (VCAs) which enable users to adjust the attenuation on each of the two bands.

The CER0286A has a wide range of applications in Wi-Fi, WiMax and cellular base station systems. It is optimized for signal filtering in both uplink and downlink directions, providing a cost-effective solution for separating and combining multiple frequency signals. Additionally, it can be used in any system where two signals should be combined with separate passbands or split into two different frequencies.

In conclusion, the CER0286A is an ideal choice for RF diplexer applications. Its compact size and low power consumption make it an excellent solution for space-restricted systems. Its adjustable gain and signal level control make it easy to use, and its adjustable passbands and two independent VCAs provide durable and reliable performance.
