Teledyne e2v HiRel, a Teledyne Defense Electronics subsidiary, has released a new radiation tolerant, passive diode Double-Balanced Mixer for operation from 18 to 46 GHz. The new product, model TDMX011037, offers engineers in the space design community a mixer with very low conversion loss, high linearity, and a wide IF bandwidth MMIC for K- and Ka-band communication links.This RF mixer is also ideally suited for use in designing an up or down-conversion stage in signal chains for radar, satellite transponders, and related RF communications circuits deployed in electronic warfare applications. The rad-tolerant mixer in die form is electrically screened to meet datasheet parameters and each wafer lot has been qualified per MIL-PRF-38534 Class K for use in demanding, high-reliability space environments. Importantly, as a passive mixer, it does not require one or more supply voltages as do its active-mixer counterparts.The double-balanced circuitry delivers outstanding port isolation while the internal 50-ohm matching simplifies its application for customer ease-of-use.Key Specifications of the Mixer:Low Conversion Loss: 6.5 dBHigh Linearity: 20 dBm IIP3Wide IF Bandwidth: dc to 20 GHzDie Size: 1.15 x 0.97 x 0.10 mmRoHS CompliantThe mixer is also a good fit for test and measurement, microwave radio, and long term GEO-Sat space applications. The product line is available for order and shipment.Teledyne was planning to showcase the TDMX011037 RF Mixer along with its complete RF portfolio at the SATELLITE 2020 event in Washington DC from March 10-12. However they decided not to attend the event due to the coronavirus outbreak.

As passed by the Legislature, the bill contains appropriations for fiscal year 2018 totaling $1.4 billion, including $122 million in unrestricted general funds and $28 million in designated general funds. The bill assures funding for the most urgent state, school district, and university facilities maintenance projects. It also includes money for statewide domestic violence shelter improvements, and to construct a new school for the Kivalina community, fulfilling the State’s legal obligations. This capital budget funds our roads, airports, and marine highways thanks in large part to federal dollars, and through reallocating dollars remaining from older projects. The bill leverages nearly $1.2 billion in federal dollars for transportation, village water infrastructure, energy, and housing projects. SB 23 is the smallest capital budget enacted since the year 2000. The capital budget also maintains the statewide radio system for local, state, and federal public safety officers and first responders. In addition, $42 million remains in two separate appropriations for infrastructure and transportation improvements in Juneau and the greater Lynn Canal area. Governor Walker: “The legislature came together in a spirit of bipartisanship to pass this legislation, and I’m glad to honor their cooperative agreement by signing the capital budget without vetoes. However, our work is not yet done. We need new revenues to address our fiscal crisis and put Alaska back on a path towards stability. We cannot cut – or veto – our way out of this crisis. I look forward to continuing to engage with the legislature to resolve Alaska’s fiscal shortfall. Alaskans deserve to have this issue resolved now.” The bill includes funds to start the Izembek road project, a priority of the residents of King Cove for decades, and seed funding to progress numerous North Slope infrastructure improvements and resource development under the Arctic Strategic Transportation and Resources (ASTAR) project.
