  • A152 Broadband Attenuator Relay
    be several times larger in size than the relay, particularly at high power. This approach increases the total package size and limits the frequency response of the attenuator. ./1dfa8b80-65b4-4581-9eb5-8e1ddcb03b91 New Attenuator Relay Design Improves. Performance in Ultraminiature Package
  • Variable Attenuator for Lasers
    design for high. power. Compared to zero-order quartz wave-plates,. where I0 is the input intensity, and θ is the angle between. achromatic quartz MgF. the beam’s initial direction of polarization and the axis of the. 2. wave-plates offer excellent. retardation accuracy over broad wavelength ranges
  • Programmable Attenuators for Wireless Products
    . Programmable attenuators are used. non-latching switch requires constant. 32 dB cells to the 64 dB cell alone. If. configurations, and switching. throughout the electronics industry. power to the solenoid to hold the. each of the first cells is 0.1 dB high. requirements, which are all accessible
  • Intermodulation Distortion in Programmable Attenuators
    complex digital modulation schemes, increased chan-. ing distortion produced by cables, attenuators and other passive. nel capacity, high transmit power and extremely low receiver. devices. Although the system is capable of measuring both,. sensitivity have put into question the linearity of passive
  • Attenuator & Termination Matching for Ferrite Junction Isolators
    be most effective when placed close to the ferrite. For this example the real. part of the impedance is too high compared to the termination. It has been assumed in these examples that the. termination is placed close to the isolation port. If the loop, when viewed on smith chart, is very small
    . the entire operating frequency range. To carry out such measurements with good accuracy requires a set of high-power,. broadband bias tees and good matching techniques. The test set-up is shown in the MIL- A-3933 document. Case 3: TCA of Switched Programmable Attenuators. Switched Programmable
  • Secure Attachment in Pulsed Power Applications
    In applying high power attenuators and terminations to RF and Microwave circuits there are a number of requirements to be observed to obtain satisfactory life. These are heat-generating devices so the removal of excess heat is key to maintaining a safe film temperature. This heat removal is often
  • High Spur Free Dynamic Range RF Photonic Links allow MIL SATCOM and RF Distribution Networks to Leverage Optical Communication Infrastructure (.pdf)
    technology to the civilian and defense markets provided limited deployment options due in large part to their high costs, limited RF performance envelope, and prohibitive size, weight and power (SWaP) requirements. In addition to these technical limitations, there existed the ever present cultural
