“…Performance characteristics of the proposed RFPA with active inductor-based output matching network in comparison with some other works [3,[17][18][19] are summarized in Table 3. Although the output power of the proposed RFPA is lower than that in [17][18][19], its required input power is lower than [18,19], while it has reached to a maximum PAE of 70%.…”

a b s t r a c tThis paper presents the use of a new structure of active inductor named cascoded flipped-active inductor (CASFAI) in a T-type high-pass tunable output matching network of a class-E RF power amplifier (RFPA) to control the output power and enhance the efficiency. The designed CASFAI behaves as an inductor in the frequency range of 0-6.9 GHz, and has reached to a maximum quality factor of 4406, inductance value of 7.56 nH, 3rd order harmonic distortion better than À 30 dB for 0 dBm input power, while consumes only 2 mW power. In order to consider the performance of the proposed active inductor-based tunable output matching network on the output power level and power added efficiency (PAE) of RFPA, the CASFAI is applied as a variable inductor to the output matching network of RFPA. The overall circuit is designed and validated in ADS in a 0.18 mm CMOS process and 1.5 V supply voltage. The results indicate that by increasing the inductance value of the matching network in constant operating frequency, the PAE peak moves from high power to low power levels without any degradation. Therefore, it is possible to maintain the power efficiency at the same maximum level for lower input drive levels.

“…Low noise figure and high linearity are important figures of merits for designing an LNA [2] which can also be used for Worldwide Interoperability for Microwave Access (WiMAX) apps [3][4]. LNA and PA designs can be with chips as well as with transistors such as Complementary Metal Oxide Semiconductor (CMOS), heterojunction bipolar transistor (HBT), field-effect transistor (FET), High-electronmobility transistor (HEMT) and Pseudomorphic High Electron Mobility Transistor (pHEMT) [5][6]; the biasing is prominent for the selection [7]. The waves emitted from the antenna have to be 1556 amplified first with PA and it is essential to form a stable [8] and efficient [9] circuit according to practice.…”

WLAN applications operating at a frequency of 2.45 GHz are a frequently used communication method in transmission tools. The connection functions to send and receive data between access points and smart devices are also fulfilled by WLAN technology. Communication quality in data transfer gains importance for this technology at every stage. Front-end module structures are used to increase such quality affects directly the efficiency. Circuits including power amplifier (PA), low noise amplifier (LNA), antenna and filter are the most significant components compose front-end structures. In this study, PA and LNA using PW570 gain block & BFP760 RF transistor circuit respectively are proposed. By means of the usage of the proposed circuits, there will be considerable improvements in data communication speed and area of coverage, which are among the WLAN performance factors.
