HMC882LP5E v00.1209 FILTERS - TUNABLE - SMT 3 FILTER - TUNABLE, LOW PASS SMT 4.5 - 7.6 GHz Typical Applications Features The HMC882LP5E is ideal for: Fast Tuning Response • Test & Measurement Equipment Excellent Wideband Rejection • Military, RADAR & EW Single Positive Frequency Control: 0 to +14V • SATCOM & Space Low Insertion Loss & User Selectable Cutoff Frequency • R&D Laboratories Single Chip Replacement for Mechanically Tuned Designs 32 Lead 5x5 mm SMT Package: 25 mm2 Functional Diagram General Description The HMC882LP5E is a MMIC low pass filter which features a user selectable cutoff frequency. The cutoff frequency can be varied from 4.5 to 7.6 GHz by applying a single analog tuning voltage between 0 and 14V. This low pass filter provides a low 2.9 dB insertion loss, 10 dB return loss and 1.23 x ƒcutoff stopband attenuation of >20 dB. This tunable filter can be used as a much smaller alternative to physically large switched filter banks and cavity tuned filters. The HMC882LP5E has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications. The low pass tunable filter is packaged in a RoHS compliant 5x5mm QFN leadless package. Electrical Specifi cations, TA = +25°C Parameter Passband Min.

[2] Optimum residual phase noise performance requires the use of a low noise driver circuit. [3]Tuning speed is dependent on driver circuit. Data measured with a high speed op-amp driver and includes driver slew rate delay. 3-8 For price, delivery and to place orders: Hittite Microwave Corporation, 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com Application Support: Phone: 978-250-3343 or [email protected] HMC882LP5E v00.1209 FILTER - TUNABLE, LOW PASS SMT 4.5 - 7.6 GHz Broadband Insertion Loss vs. Control Voltage 3 Broadband Return Loss vs. Control Voltage 0 0V 7V 7V -20 RETURN LOSS (dB) INSERTION LOSS (dB) -10 14V 0V -30 -40 -50 -10 14V -20 S11 S22 -30 -60 -70 -40 0 5 10 15 20 25 30 0 5 10 FREQUENCY (GHz) 15 20 25 30 FREQUENCY (GHz) Insertion Loss vs. Control Voltage [1] Return Loss vs. Control Voltage [1] 0 0 7V -3 RETURN LOSS (dB) INSERTION LOSS (dB) 0V 7V 14V 0V -6 -9 -10 FILTERS - TUNABLE - SMT 0 14V -20 -30 S11 S22 -12 -40 0 1 2 3 4 5 6 7 8 9 10 0 1 2 3 5 6 7 8 9 10 Return Loss vs. Temperature, Vfctl @ 7V [1] 0 0 -3 -10 RETURN LOSS (dB) INSERTION LOSS (dB) Insertion Loss vs. Temperature, Vfctl @ 7V [1] -6 +25C +85C -40C -9 4 FREQUENCY (GHz) FREQUENCY (GHz) +25C +85C -40C S11 -20 -30 S22 -40 -12 0 1 2 3 4 5 6 7 8 0 1 FREQUENCY (GHz) 2 3 4 5 6 7 8 FREQUENCY (GHz) [1] Low frequency performance limited by external DC blocking capacitors at RF input and output.
