HMC896LP4E was also designed for optical networking and instrumentation applications.

The HMC896LP4E is unique in its ability to serve as both a low-noise low-power amplifier and an active filter. Depending on the application, the user can select the best impedance match circuit. By combining an active amplifier and filter network, the HMC896LP4E is able to offer superior performance at an attractive price.

The HMC896LP4E is also extremely flexible, allowing customers to customize the amplifier performance without having to design their own active filter circuitry. With a few clicks of a mouse, customers can program in frequency response, gain, input/output return loss and linearity. The flexibility offered by the device means that customers can realize cost savings and improved performance over traditional amplifier solutions.

General Description of Working Principle
The HMC896LP4E is an active programmable amplifier built with a cascaded amplifier/filter topology that combines an amplifier and a filter. The device has two amplifier stages with a bandpass filter in between. The first stage amplifier is used to provide the desired signal gain and the second stage amplifier is used to shape the frequency response of the signal. The bandpass filter is used to reduce noise and other unwanted distortion between the two stages.

The HMC896LP4E has a high linearity, low noise performance and can provide gain up to 24 dB. Thanks to its unique programmable architecture, customers can easily adjust the amplifier parameters and enable or disable the filter as required. This programmability makes the HMC896LP4E an ideal solution for a broad range of applications.
