The Wilkinson Microwave Anisotropy Probe
The Wilkinson Microwave Anisotropy Probe (WMAP) has mapped the full sky in five frequency bands between 23 and 94 GHz. The primary goal of the mission is to produce high-fidelity, all-sky, polarization-sensitive maps that can be used to study the cosmic microwave background. Systematic errors in the maps are constrained to new levels: using all-sky data, aspects of the anisotropy may confidentl...
متن کاملThe PRO1 ASIC for Fast Wilkinson Encoding
Wilkinson conversion of stored samples in large Switch Capacitor Array (SCA) ASICs, such as used for high speed waveform sampling, has many benefits in terms of compactness, no missing output codes, low power requirements and robustness. However such Analog-toDigital conversions are relatively slow, limited by the encoder clock speed. By repeating the same fast sampling technique used by the SC...
متن کاملMiniaturization of Broadband Wilkinson Power Dividers
Received Jan 5, 2018 Revised Mar 3, 2018 Accepted Mar 20, 2018 This paper proposed three modified Wilkinson power dividers in order to achieve a size reduction and a wide bandwidth. The first structure presented the power divider using compact folded step impedance transmission lines rather than the uniform microstrip line design for operating center frequency of 3 GHz. The second structure sho...
متن کامل[subcorneal Pustular Dermatosis. (sneddon-wilkinson Disease)].
Subcorneal pustular dermatosis is a disease that has coalescent, flaccid, recurrent pustules. We do not know everything about its etiology or pathogenesis; however, its autoimmune mechanism links it with neoplastic or immunologic diseases. First line treatment is dapsone. We describe the case of a classic subcorneal pustular dermatosis in a patient in who we could not use dapsone (sulpha drugs ...
متن کاملWilkinson Power Divider with Ebg Cpw
A 6 : 1 unequal Wilkinson power divider that combines the advantages of a coplanar waveguide with an electromagnetic bandgap (EBG CPW) and microstrip line structures suitable for a PCB circuit design is proposed. The highly characteristic impedance transmission line (TL) is realized by employing the proposed EBG CPW structure, which is difficultly achieved using the conventional microstrip line...
