A 77 GHz Front-End Receiver for Antenna Arrays
SiGe bipolar technologies have proven to be viable candidates for integrated circuits operating at very high frequencies, due to consistently increasing cutoff frequencies of the transistors. While millimeter wave (MMW) integrated circuits have traditionally been implemented in GaAs or InP, the advancement of silicon technologies has recently enabled silicon-based ICs with promising and cost-ef...
متن کاملToward Realization of 2.4 GHz Balunless Narrowband Receiver Front-End for Short Range Wireless Applications
The demand for radio frequency (RF) transceivers operating at 2.4 GHz band has attracted considerable research interest due to the advancement in short range wireless technologies. The performance of RF transceivers depends heavily on the transmitter and receiver front-ends. The receiver front-end is comprised of a low-noise amplifier (LNA) and a downconversion mixer. There are very few designs...
متن کاملLow-cost Vector Network Analyzer for Biomedical Applications
A low-cost and portable vector network analyzer (VNA) which covered operating frequency between 1MHz to 3GHz is used for vector reflection coefficient and standing wave ratio (swr) of the various microstrip antennas. This paper presents measurements of various ultra wideband (uwb) microstrip antennas for applications in biomedical field. Selection of antenna is an important key for detection of...
متن کاملA transformer-loaded receiver front end for 2.4 GHz WLAN in 0.13 m CMOS technology
A 2.4 GHz radio frequency receiver front end with an on-chip transformer compliant with IEEE 802.11b/g standards is presented. Based on zero-IF receiver architecture, the front end comprises a variable gain common-source low noise amplifier with an on-chip transformer as its load and a high linear quadrature folded Gilbert mixer. As the load of the LNA, the on-chip transformer is optimized for ...
متن کاملA 1.57-GHz RF Front-End for Triple Conversion GPS Receiver
A low-power, 1.57-GHz RF front-end for a global positioning system (GPS) receiver has been designed in a 1.0m BiCMOS technology. It consists of a low noise amplifier with 15 dB of gain, a single balanced mixer with 6.3 mS of conversion gm, a Colpitts LC local oscillator, and an emitter coupled logic (ECL) divide-by-eight prescaler. This front-end has a singal sideband (SSB) noise figure of 8.1 ...
