Filed:

Jul 30, 2008

Appl. No.:

12/220993

Inventors:

James A. Carr - Fountain Valley CA, US
Tamrat Akale - Azusa CA, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

H01P 1/32

US Classification:

333 11, 333 242

Abstract:

A surface mount circulator. The novel circulator includes a substrate, a predetermined number of microstrip lines disposed on a first surface of the substrate, a ground layer and a predetermined number of electrical contacts disposed on the second surface of the substrate, and a mechanism for coupling each microstrip line to one of the electrical contacts. In an illustrative embodiment, the circulator uses edge wrap metallization to wrap a microstrip line down a side of the substrate to connect with a corresponding contact. A ball grid array can then be used to connect the signal contacts and ground at the second surface of the substrate with a circuit board. The circulator also includes a magnet on first surface of the substrate over a resonator circuit connecting the microstrip lines and a pole piece on the second surface of the substrate beneath the ground to provide magnetic bias to the substrate.

H01Q 1/50

US Classification:

343787

Abstract:

The present invention relates to active electronically scanned array antennas. A thin, low cost design is provided by coupling electromagnetic energy into periodically driven long slots () using circulators with integrated probes (). The long slots () are formed as grooves () in a conductive base plate (), each groove () bracketed on both sides by conductive strips (). The circulators with integrated probes () are installed between the conductive strips () and the base plate (), to reduce fabrication costs of the machined parts and to facilitate the making of connections between the circulators and the antenna electronics. The probes () protrude partway into the slots () and provide coupling to waves propagating in free space.

Abstract:

An integrated differential high power amplifier-radiator array that overcomes the prior art impedance match issues is described. An impedance matching balun is used to feed a high output impedance, differential HPA, which in turn drives a wide band radiator or array of radiators having a matching input impedance to provide a highly efficient, compact transmit system. In one exemplary embodiment, the HPA may be a high impedance Class-B HPA configured as a push-pull cascode amplifier. A high impedance isolator or circulator may be used between the HPA and the radiator. One of ordinary skill in the art will readily appreciate that a receive implementation, using a properly matched low noise amplifier in place of the HPA, is also possible. Similarly, with the addition of a slotline circulator, transceiver operation is also attainable with the addition of an impedance matched receive chain.

International Classification:

H01Q 13/10

US Classification:

343770

Abstract:

An antenna is provided and includes a radiator aperture assembly including a plurality of radiator sticks, each radiator stick including a row of radiating elements configured to transmit and receive RF energy and a body having opposite sides, conductive elements coupled to the radiating elements and a plate disposed proximate to the radiator aperture assembly through which the conductive elements extend. Complementary opposite sides of the respective bodies of adjacent radiator sticks and a surface of the plate are configured to form a slot radiator.

US Classification:

606 79

Abstract:

A patella cutting clamp comprises a pair of jaw members joined together in scissors-like relation for pivotal movement relative to each other about a pivot axis intermediate their ends. Each jaw member has a handle portion extending in one direction from the pivot axis and a jaw portion extending in the other direction. The jaw portions have edges facing each other that are shaped for engagement with opposite borders of a patella. Teeth along the patella-gripping edges grip and hold the patella firmly. Saw guide slots in the jaw portions lying in a common plane guide the saw when the saw cut is made. A patella elevator member is attached to the jaw members for movement along the pivot axis and has a platform portion adapted to engage the anterior aspect of the patella. A mechanism is provided for establishing and maintaining a predetermined position of the elevator member relative to the jaw members and thereby positioning the patella at a predetermined position relative to the saw guide slots. Another mechanism holds the jaw members in an adjusted position relative to each other with the jaw portions engaging and holding the patella.
