The HMPS-2822-TR1 is a part of the family of RF PIN diodes, commonly used in applications to attenuate microwave signals. It is a high reliability part and is capable of providing a maximum continuous power rating at all frequencies up to 500 MHz. An application field where HMPS-2822-TR1 can be used is in Transmitter/Grabber Filters, Amplifiers and Oscillators, Microwave Sensor Systems, Wideband circuits, Tape Recorder Power Supply, Attenuators, and so on. Additionally, these types of RF PIN diodes also feature a low noise figure and low input capacitance and resistance. As a result, they are suitable for use in wideband amplifier applications, as well as applications that involve low power communication systems. The basic function of the HMPS-2822-TR1 RF PIN diode is based on its capacitance-voltage relation and the reverse-voltage breakdown characteristic. The diode has two electrodes, a control and a counter electrode, which are electrically connected in parallel and separated by a thin insulation layer. By changing the voltage, which is applied between these electrodes, the device’s capacitance can be changed. In the reverse-voltage breakdown region the device’s capacitance increases rapidly. The resistance of the diode also changes with the voltage, increasing with higher reverse voltages. The HMPS-2822-TR1 also features a low input capacitance and resistance. This is extremely beneficial as it reduces losses, as well as distortion, owing to lower input impedances. Moreover, it ensures better immunity to external RF and microwave noise, which translates into better performance. When connected to an amplifier, the device is capable of providing a very broad range of attenuation (from 0 to 31 dB). Moreover, its wide range of attenuation can be obtained over the frequency range of 430 - 500 MHz. Additionally, this device can also operate over the temperature range of 0-70 ⁰C with a very low distortion. Therefore, the HMPS-2822-TR1 is an ideal solution for circuit applications where wide-range microwave attenuation, low distortion and low power capability are needed. This device delivers good performance at all frequencies, resulting in a wide range of applications. It is also highly reliable and can withstand extreme temperatures and conditions, making it suitable for commercial and military applications.
