UTP 28SP 135BL is a combination of a bipolar, linear AF/RF amplifier and a driver amplifier. It is ideal for use as a driver amplifier for low power audio preamps, medium power audio amplifiers, and RF transmitters. The UTP 28SP 135BL offers a high bandwidth and low distortion characteristics that are not available in other amplifier packages.

The UTP 28SP 135BL has a wide variety of applications, including audio and RF amplifier, receiver, transmitter, and preamplifier applications. Depending on the specific application, the UTP 28SP 135BL may be operated in either single ended or push pull configuration. It is also useful for audio filtering and for driving headphones and small loudspeakers. In receiver applications, it is used to amplify received or transmitted signals from a base station or mobile radio.

The UTP 28SP 135BL is packaged in an 8-lead dual-in-line package (DIP) with a top contact or wire bonding option. It is available in through-hole and surface mount packages and is available in standard and enhanced versions. The enhanced version has improved performance characteristics, such as lower distortion and better power handling.

The UTP 28SP 135BL has two amplifying stages and is designed to provide variable gain adjustment with a single control. This control allows the user to select the desired gain settings for the amplifier. The output stage can provide up to 27 dB of gain and the input stage can provide up to 10 dB of gain.

The UTP 28SP 135BL works on the principle of feedback. The input signal is provided to the input of the amplifier, which then provides a feedback signal to the output stage that is proportional to the input signal. This signal is then amplified and fed back to the input stage. The amount of feedback is determined by the gain setting that is selected by the user. As the gain is increased, the amount of feedback increases, resulting in an increase in gain. Likewise, when the gain is reduced, the amount of feedback decreases, resulting in a reduction in the gain.

The UTP 28SP 135BL is a versatile amplifying device that can be used for a variety of audio and RF applications. Its small size and low power consumption make it ideal for battery-powered applications. It also offers a high bandwidth and low distortion characteristics, making it well-suited for high fidelity audio applications. The adjustable gain control allows it to be used for various RF and audio applications. The UTP 28SP 135BL is an ideal candidate for a variety of audio, RF, and preamplifier applications.
