HMC5805LS6TR

RF amplifiers are one of the most important components in modern wireless communication. They are used to amplify or manipulate the transmitted radiofrequency (RF) signals so that they are transmitted accurately over long distances. The HMC5805LS6TR is a monolithic RF amplifier integrated circuit that is designed for broadcast applications requiring high linearity. It is a dual-channel device that operates over a wide frequency range from 50 to 6000 MHz and provides 57 dB of gain with a low noise figure.

In order to understand the HMC5805LS6TR application field and working principle, it is important to understand its primary components and features. The IC consists of two identical stages comprising an amplifier, a low-noise switch, and two identical signal handling stages. Each of the two amplifier stages exhibits an unconditional stability up to a frequency range of 6000 MHz. The amplifier is optimized for maximum gain and linearity, providing a high 3rd-order intercept point of 90 dBm. The low-noise switch is included for switched-mode applications such as channel selection. The output also features a wide output match for both the source and drain, which allows for direct connection to the RF chain.

The HMC5805LS6TR can be applied in an endless number of scenarios, such as high-speed point-to-point links, wireless local area networks, wide area networks, terrestrial broadcast links, satellite dish receivers and cell phone towers. It can also be used for Wi-Fi receivers, UHF/VHF, TV broadcasting and more. The amplifiers have high linearity and are well suited for a wide range of frequencies. Depending on the application, the HMC5805LS6TR may be used as a stand-alone solution or as part of an integrated system.

The circuit also has a unique feature known as the I-V Adjust pin. This adjustable current-to-voltage (I-V) adjustment provides a means to adjust the gain of the amplifier as it provides a stable output level regardless of supply voltage variations. This feature allows for a better signal-to-noise ratio and ensures more consistent performance over a wide range of frequencies and temperature variations.

Another key feature of the HMC5805LS6TR circuit is the high-power capability. It is capable of providing a maximum output power of +24dBm at a frequency of 6000MHz while operating at 3.3v which is more than enough for many broadcast applications. The IC is also capable of operating in class AB mode providing added linearity.

In conclusion, the HMC5805LS6TR is an excellent choice for many broadcast applications. It has a wide frequency range of 50 to 6000 MHz, offers 57db of gain with a low noise figure, and can provide up to 24dBm of output power. It has an adjustable I-V adjust pin for a stable output level, and is capable of operating in class AB mode. The IC’s feature set makes it well suited for a wide range of applications, from Wi-Fi receivers to UHF/VHF broadcasting and more.
