HERITAGE. SPDT Dow-Key’s innovative and proven high reliability, superior RF performance, and low current/magnetic latch SPDT switches have played a part in hundreds of successful space missions since the 1970s. Some of these missions include: GPS III (Global Positioning System), Atlas (launch vehicle), Pegasus (rocket), Milstar (satellite communication system), and Optus (leading operator of satellites in the Asia Pacific region). 421H SPDT 426H SPDT 401H SPDT Series* 401H 401HY 401HY 402H 406H 406H 421H 426H 818 909 Description Frequency GHz SPDT, Low Power DC-22 SPDT, Low Power DC-27 SPDT, Low Power DC-40 SPDT, High Power DC-10 SPDT, Medium Power DC-12 SPDT, High Power DC-10 2/3, Low Power DC-22 2/3, High Power DC-10 SPDT, High Power DC-6 SPDT, Low Power DC-18 VSWR (max) 1.45 1.45 1.75 1.50 1.50 1.50 1.45 1.45 1.30 1.50 Isolation dB (min) 65 60 55 60 60 60 60 60 60 60 Ins.

On other space missions like the ACE (Advanced Composition Explorer – an explorer mission), our lightweight (less than 55 grams) and highly reliable qualified transfer switches were a perfect fit. 707 DPDT 411HQ DPDT Series* 700 707 411H 411HQ 4113HAC Description Frequency GHz DPDT, Medium Power DC-10 DPDT, Low Weight DC-18 DPDT, Low Power DC-18 DPDT, Low Weight DC-27 DPDT, High Power 1.25-1.65 VSWR (max) 1.45 2 1.50 1.45 1.20 Isolation dB (min) 60 60 60 65 60 Ins.

T-Switch The benefit of a T-switch over a transfer switch is that up to three combinations of RF paths are available, which is perfectly suited for space applications where more than two path combinations (DPDT) are required. In addition to superior RF performance and lightweight/high power capabilities, Dow-Key distinguishes itself from others by introducing random drive (minimizing the switching time) rather than forcing the application to switch RF paths in sequential order. These switches have been qualified in programs including MUOS (space craft), Isro (Indian Space program), and Insat-3 (multipurpose satellite design providing telecommunications, television broadcasting, meteorological, search and rescue services).

Dow-Key Microwave • www.dowkey.com • 800.266.3695 Waveguides: DPDT (Transfer) In 1993 Dow-Key expended its involvement in Hi-Rel space programs with the acquisition of the Transco Space Qualified Products from Datron/Transco Systems in Southern California, including space programs dating back to 1968. In addition to inheriting many of the Hi-Rel (and commercial) waveguide switches, many of the veteran Transco design engineers stayed with Dow-Key and are still employed with us today. Thus, this unique combination of experience and innovation enhances our capabilities. The waveguide switches listed below were included in high profile space missions such as Kepler (flight system) and Deep Impact (NASA space probe). 33D13700 WR-15 33C96600 WR-34 Part Number 33D13700 33C98100 33C96600 33C96100 33C96000 33C94100 33C51200 33C51400 Waveguide Size WR 15 WR 28 WR 34 WR 42 WR 62 WR 75 WR 90 WR 112 Dimensions (inches) 2.225 x 3.765 x 1.850 2.045 x 3.035 x 2.045 1.510 x 2.510 x 1.510 2.042 x 3.424 x 2.042 1.810 x 3.414 x 1.810 2.640 x 4.060 x 1.880 2.637 x 3.900 x 1.875 2.173 x 4.400 x 2.175 33C98100 WR-28 Actuator Type Latching Latching Latching Latching Latching Latching Latching Latching Note: Other configurations are available including “R” Dow-Key Microwave • www.dowkey.com • 800.266.3695 Voltage (Vdc) 28 28 28 28 28 28 28 28 Mass (grams) 180 158 150 135 150 140 360 490 Switch Block Over the years, Dow-Key’s outstanding Hi-Rel track record has generated interest in combining space qualified switches and other components such as power dividers in a block of switches to achieve the matrix complexity needed in programs such as GPS-3, Kompsat-3 (satellite), Inmarsat-4, and other classified programs. Experience gained in over 150 years of combined knowledge and practice in design, test, and manufacturing of Hi-Rel products, makes Dow-Key a perfect investment for custom and complex switching needs.
