X Band, Digitally Tunable, High-Pass Filter and Low-Pass Filter Enhanced Product ADMV8913-EP FEATURES GENERAL DESCRIPTION Digitally tunable, lower and upper 3 dB cutoff frequencies The ADMV8913-EP is a fully monolithic microwave integrated Optimal wideband rejection: 35 dB circuit (MMIC) that features a digitally selectable operating Single chip replacement for discrete filter banks frequency. The device has an integrated high-pass filter (HPF) and Compact 6.00 mm 3.00 mm 0.89 mm LGA package an integrated low-pass filter (LPF) that allows a pass-band response within the 6.6 GHz to 11.9 GHz frequency range. ENHANCED PRODUCT FEATURES The flexible architecture of the ADMV8913-EP allows for the 3 dB Supports defense and aerospace applications (AQEC standard) cutoff frequency (f3dB) of the high-pass and the low-pass filter to be Military temperature range (such as 55C to +105C) controlled independently. The digital logic control on each filter is Controlled manufacturing baseline 4 bits wide (16 states) and controls the on-chip reactive elements to One assembly/test site adjust the f3dB. The typical insertion loss is 5.3 dB, and the One fabrication site wideband rejection is 35 dB, which is ideally suitable for Enhanced product change notification minimizing system harmonics. Qualification data available on request This tunable filter can be used as a smaller alternative to large APPLICATIONS switched filter banks and cavity tuned filters, and the ADMV8913-EP provides a dynamically adjustable solution in Test and measurement equipment Military radar and electronic warfare and electronic advanced communications applications. countermeasures Satellite communications Industrial and medical equipment FUNCTIONAL BLOCK DIAGRAM 30 29 28 27 26 25 24 23 22 21 PARALLEL HIGH-PASS LOW-PASS LDO GND 1 20 GND SELECT FILTER LOGIC FILTER LOGIC ENABLE ADMV8913-EP GND 2 19 GND RF1 3 18 RF2 GND 4 17 GND CHIP SPI LOGIC AND MODE LDO RESET LOOKUP TABLE SELECT +2.5V GND 5 16 GND 6 7 8 9 10 11 12 13 14 15 Figure 1.
