Attenuators are devices which are used to reduce power or voltage levels within an electronic system. The ATT-0298-15-HEX-02 is a specific, narrowband, pin diode attenuator which operates at a frequency range of 0.3-22GHz. It is designed to provide a power reduction from -15 dB minimum to -90 dB maximum. Due to its wide range of attenuation levels, the ATT-0298-15-HEX-02 can be applied in a variety of settings.

Application Field

The GENERAL MICROWAVE ATT-0298-15-HEX-02 from Pasternack is used in a range of applications. It is useful in a multitude of fields such as radar, communications, and other analog/RF applications. It is employed in situations where amplitude level needs to be regulated as well as in the suppression of interfering signals, ensuring clearer transmission of the desired signals.

In communications systems, it can be used as a leveling element for setting, controlling, and maintaining levels in an array of transmitting and receiving equipment to prevent damaging the system hardware. A similar application is used in computers and software where input levels must be controlled to prevent overloads or underloads.

The ATT-0298-15-HEX-02 also finds use in aerospace applications, such as in aircraft emergency radio systems, where it controls transmit and receive levels to provide a signal-to-noise ratio (SNR) for reliable communication.

Working Principle

The ATT-0298-15-HEX-02 operates on the principle of DC bias protection. This is when the incoming RF signal is divided among two paths, one of which is at a specific DC bias level. Some of the signal passes through this path, while the rest of the signal is attenuated and sent through the second path. The DC bias level is variable, and determines the amount of attenuation. Thus, the system functions like two variable attenuators in series.

The device is offered in two packages: a standard-sized package with a nominal height of 13.5mm and a miniature package measuring 8.5mm. The ATT-0298-15-HEX-02 is designed to operate at a bandwidth of 0.3-22GHz with a maximum VSWR value of 1.7:1. It has an operating temperature range of -55 to 85 degrees Celsius and draws a maximum DC current of 250 mA.

In summary, the ATT-0298-15-HEX-02 is a narrowband, pin diode attenuator designed to provide a power reduction from -15 dB minimum to -90 dB maximum. It is suitable for a variety of applications, including communications, radar, aerospace, and other RF/analog applications. It operates using the principle of DC bias protection and has a wide operating temperature range.
