This paper presents a tool capable of automatically compiling the circuit of a direct-conversion receiver at the schematics level based on system specifications that include the frequency of operation, gain, noise figure, IIP2 and IIP3 linearity. The front-end of a direct-conversion receiver is ...
GPS Triple-band receiver RF front-end CMOS integrated circuit IMRR 1. Introduction Recently, the global positioning system (GPS), which was originally developed for military purposes, is widely used to obtain location information for applications such as car navigation systems. The widespread use of...
Analog Devices’ RF power linearizer (RFPAL) devices feature a programmable analog signal processing architecture that effectively combines digital programmability with the simplicity, small size, and low power consumption of analog circuit design. The benefit provided by this architecture is a predistortio...

The AD9081 and the AD9082 mixed signal front-end (MxFE®) devices are high-performance, highly-integrated RF digital-to-analog converters (DAC) and RF analog-to-digital converters (ADC) used in many applications. Both contain four 16-bit, 12 GSPS maximum sample rate DAC cores. The AD908...
low loss operation of a Butler matrix at 77 GHz is possible. A Butler matrix may be combined with an antenna array on a single substrate. An improved RF front end includes an REF circuit, a Butler matrix, and an antenna array. Examples include a Butler matrix for 77 GHz automotive radar...
NXP Semiconductors Data Sheet: Advance Information 76-77 GHz RF receiver front-end for W-band radar applications Document Number: MC33MR2001R Rev. 5.0, 9/2016 MR2001R The MR2001 is an expandable three package solution for automotive radar modules. The chipset consists of a VCO (voltage ...
Finally, the other common failure mode is called front-end desensitization. This is caused when a very strong RF signal is present that is seen by the first Low Noise Amplifier. The signal can be out of the band used by the radio in question, but it’s strong enough to cause the ampli...
This module has a powerful enough on-board processing and storage capability that allows it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows...
But at high frequencies, the impedance (Z) of an RF circuit changes when measured at different distances from the load. The change also depends on the substrate used and the dimensions of the RF trace. Therefore, the trace also becomes a design element in RF schematics. T...
