The HMC158C8TR RF Misc ICs and Modules are a family of low noise amplifier (LNA) chips used for amplification across multiple frequency bands. Designed for small form factor applications, the HMC158C8TR is ideal for receiver preamplification, providing a high gain and low noise figure. This IC is well-suited for applications in communication systems, such as cellular base stations, Wi-Fi access points, and satellite receivers.

The HMC158C8TR contains an integrated preamplifier, driver stage, and output amplifier integrated into a single chip. It has an adjustable gain in multiple steps up to a maximum of 16 dB. This allows the user to precisely tailor the LNA’s gain for their system’s particular application. The noise figure is also adjustable, with a minimum of 1.6 dB and a maximum of 2.4 dB. In addition, the HMC158C8TR has a voltage-controlled current source, allowing users to further adjust the LNA’s gain.

The HMC158C8TR’s working principle is based on the same amplifier architecture as other low noise amplifiers. A signal is input into an input stage, which provides a high input impedance and low output impedance. The signal is then amplified by a driver stage, which drives the output stage. The output stage is adjusted to a specific gain by an external resistance or voltage input, providing accurate control of the desired output power. Additionally, the input and output stage are temperature compensated, providing a low temperature coefficient of gain.

The HMC158C8TR is specifically designed for low-power battery-powered applications, making it ideal for portable and wireless systems. The chip operates in a voltage range of 1.8 to 3.6 V, making it compatible with most battery-powered devices. The chip features a low power consumption of 5mA at maximum gain.

The package size of the HMC158C8TR is just 4 mm by 4 mm, making it one of the smallest LNA chips available. The HMC158C8TR is designed to offer high gain and low noise figure in a compact package, making it well-suited for applications in communication systems, especially those requiring small form factor ICs.

The HMC158C8TR is a low noise amplifier chip that is designed for small form factor applications. It provides an adjustable gain up to 16 dB and an adjustable noise figure down to 1.6 dB. Its low power and small package size make it ideal for battery-powered applications, such as access points, cellular base stations, and satellite receivers.
