An HMC-890LP5ETR is an amplified filter developed by the leading edge manufacturer, Peregrine Semiconductor. This device is a high-frequency integrated amplifier filter, offering superior performance and low noise, and produces a range of frequencies from 500 MHz to 8.9 GHz. It is suitable for use in applications that require a low noise and high dynamic range, such as cellular handsets, digital consumer electronics, software-defined radios, and wireless communication systems.

The HMC-890LP5ETR is an active filter that uses an internally tuned IF amplifier with feedback. The voltage gain of the amplifier is dependent upon the DC supply voltage, with a nominal gain of 8.9 dB at a DC power supply voltage of 3 V. The low-noise amplifier provides stable signal gain over temperature and frequency, and features a very low current consumption of only 5.3 mA. Additionally, the input-referred noise is only 5.3 dBμV, while the mismatch resistance is typically 3 dB.

The device includes a variety of features that make it suitable for a wide range of applications. It has an input impedance of 50 ohms, making it ideal for use with broadband signals that require low input impedance. Additionally, the amplifier features a high dynamic range of greater than 70 dBc, which allows it to handle large signal levels. It also has an integrated low-pass filter, which eliminates unwanted high-frequency spurious signals, providing protection from interference.

The HMC-890LP5ETR is also highly reliable, having been tested to an operational lifetime of greater than 20 years. This makes it a suitable choice for long-term applications that require a reliable signal. Additionally, the filter can be integrated into the printed circuit board (PCB) for a neat and efficient installation, thanks to the device\'s small size and low profile.

In summary, the HMC-890LP5ETR is an ideal choice for applications that require a low noise and high dynamic range, such as cellular handsets, digital consumer electronics, software-defined radios, and wireless communication systems. The device offers superior performance with a low noise amplifier and a high dynamic range of greater than 70 dBc, making it a reliable choice for long-term applications. It also features an integrated low-pass filter, which eliminates unwanted high-frequency spurious signals, providing protection from interference.
