Which high frequency manufacturer is most suitable for microwave high frequency power amplifier
At present, there are relatively low frequency bands (300MHz to 30GHz), and also include the millimeter wave band (30 to 300GHz), and also have relatively high frequency bands to adapt to the development and demand of 5G technology. The wireless communication network based on 5G technology is very different from the traditional cellular network system. When designing a power amplifier suitable for 5G technology, engineers need to deal with both RF microwave and millimeter wave. The substrate is a very important aspect.

High frequency power amplifier. In general, most 5G system applications do not operate at frequencies higher than 6 GHz. The performance of a frequency microwave 5G power amplifier depends on many key characteristics of the circuit board, including good thermal management, low insertion loss, and uniformity of RF performance over a wide temperature range. It also includes a well-controlled dielectric constant (Dk or εr). ), high thermal conductivity, low TCDk (Dk thermal coefficient), low loss factor and tightly controlled dielectric thickness. Let's take a look at each of the properties of the material and why they are critical to the characteristics of the RF microwave power amplifier
Many 5G RF microwave power amplifiers use a Doherty structure. The circuit of this structure requires the design of a quarter-wavelength line as the impedance transformation. If the wavelength-dependent PCB material variables are well controlled, the performance of the quarter-wave line circuit can be achieved as expected. Variables associated with this include material Dk and media thickness. Variable factors in the PCB manufacturing process also affect the performance of the quarter-wave line circuit, such as wire accuracy and conductor thickness. In general, high-frequency circuit boards with a Dk tolerance of ±0.05 are considered to have better performance and can be used for materials in such applications. In addition, the substrate dielectric thickness of the material should be controlled to ±10% or less. Therefore, the microwave board requires a high frequency material, a low dielectric constant, a high thermal conductivity, and a low loss substrate.
