Precision Devices DLI mmWave Solutions Moving to mmWave brings about new filtering challenges. Shrinking Wavelengths Increased Temperature At 700MHz, the wavelength in free In dense board environments temperatures rise, and space is about 430mm, and at 2.6GHz, front ends will need to operate at increased temperature wavelengths are 115mm. Yet at 39GHz, and with inherent temperature stability. wavelengths are only 7.7mm. Increased Need for Performance Repeatability Reduced Size of the RF Front End High frequency circuits are sensitive to variations in As wavelength shrinks so do antenna sizes, and performance from part to part. Repeatability in filter for arrays to avoid diffraction effects, antenna spacing component performance is key to avoid costly set at needs to be similarly shrunk. Filters in RF front ends test scenarios. need to be compact. Ever Present Need to Perform Increase In Number of RF Paths RF Front End Filter components for the mmWave RF front end need The enabling technologies for mmWave, Beam Steering and to encompass all of these factors, and they still need MIMO, rely on arrays of antennas, which in turn rely on arrays to perform to ensure the best spectral efficiency and of RF paths further necessitating compact filtering components. rejection possible.
