As people's requirements for data rates are getting higher and higher, the demand for wireless communication system bandwidth is also gradually increasing, which also promotes the further sustainable development of communication technology. The successive launches of 2G, 3G, and 4G technologies have enabled mobile services to gradually transition from a single form to a grand occasion that can simultaneously support multiple services such as voice, data, and video. At present, with the vigorous development of the 4G market, China Mobile, Telecom, and China Unicom have all obtained 4G licenses. The frequency bands obtained are as follows:
Table 1: Distribution of 4G license frequency bands of various operators
It can be seen from the above table that the frequency range of 4G covers approximately frequencies from 1700 to 2700 MHz, and a frequency span of about 1 GHz. This poses severe challenges to manufacturers of macro base stations/small base stations using traditional solutions, especially R&D personnel, mainly in the difficulty of research and development, cycle time, device portability, product size, maintainability, and material stocking. , Inventory and so on.
In response to such problems, the internationally renowned semiconductor manufacturer Infineon Technology has launched a new generation of LDMOS power amplifier products: PTFC270101. It has broadband characteristics, can cover the frequency range of 900-2700MHz, and good electrical characteristics, which can solve this problem well. It is the difference between the first stage amplifier of the macro base station power amplifier module and the final stage amplifier of the small base station power amplifier module. Second choice, especially small cell products with three-carrier requirements. At present, Shiqiang has already represented this product.
The basic characteristics of LDMOS power amplifier PTFC270101 are as follows:
It adopts plastic package, the package code is PG-SON-10, and the package form and size are as follows:
Figure 1: PTFC270101 package form and size diagram
In the test environment, VDD = 28 V, IDQ = 120 mA, POUT = 1.3 W (average power), Æ’1 = 2650 MHz, Æ’2 = 2690 MHz, test signal is 3GPP WCDMA signal, dual carrier, channel bandwidth is 3.84 MHz, 8 In the case of dB PAR @ 0.01% CCDF:
Its gain and efficiency characteristics are as follows:
