A 40 GHz power amplifier (PA) driver for the remote antenna unit (RAU) transceiver of a mm-wave radio-over-fiber (RoF) system is presented in this paper. Mm-wave RAU is proposed as a complementary technology to fiber-to-the-home to minimize costs and to increase bandwidth. In order for RoF to be feasible, the cost of the RAU must be minimized through low-cost technology such as CMOS. The PA driver...
Multilayer end coupled band-pass filters (BPFs) using Low Temperature co-fired Ceramic (LTCC) technology have been presented as a parts of 40 GHz Remote Antenna Unit Downlink for Radio over fiber (RoF) system applications. In order to control the precise distance between two adjacent resonators, the resonators was vertically located on different layers. The BPFs were designed and fabricated by using...
This paper describes the design and measured performance of Monolithic Microwave Integrated Circuit (MMIC) power amplifier for wireless LAN applications in the 2.4GHz band. The power amplifier (PA) is designed using 0.15μm GaAs power PHEMT technology. The die size of this PA is 1.2mm × 0.7mm and this PA is also offered in 16-pin QFN package. With only 3.0 V of drain voltage (VDS), the packaged PA...
This paper describes the design and measurement of a medium power amplifier (MPA) using 0.15 μm GaAs PHEMT technology for wireless application. At 2.4 GHz and 3.0 V of VDS, a fabricated MPA exhibits a P1dB of 15.20 dBm, PAE of 12.70% and gain of 9.70 dB. The maximum current, Imax is 84.40 mA and the power consumption for this device is 253.20 mW. The die size of this amplifier is 1.2 mm...
This paper presents a CMOS fully differential folded cascode that operates at high frequency. Theoretical study on this amplifier is first presented and analyzed. The crucial parameters that may have influences on the trade-off for the design of this amplifier are also presented. Simulation results showing the characteristics of this amplifier are discussed. Using technology CMOS 0.18 μm with power...
