| HMC882LP5E v00.1209 FILTER - TUNABLE, LOW PASS SMT 4.5 - 7.6 GHz 3 FILTERS - TUNABLE - SMT Typical Applications The HMC882LP5E is ideal for: * Test & Measurement Equipment * Military, RADAR & EW * SATCOM & Space * R&D Laboratories Features Fast Tuning Response Excellent Wideband Rejection Single Positive Frequency Control: 0 to +14V Low Insertion Loss & User Selectable Cutoff Frequency 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 cutoff 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.

[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 apps@hittite.com HMC882LP5E v00.1209 FILTER - TUNABLE, LOW PASS SMT 4.5 - 7.6 GHz Broadband Insertion Loss vs. Control Voltage 0 -10 7V -20 0V -30 -40 -50 -60 -70 0 5 10 15 20 25 30 -40 0 5 10 15 20 25 30 14V Broadband Return Loss vs. Control Voltage 0 3 FILTERS - TUNABLE - SMT 3-9 0V INSERTION LOSS (dB) 7V RETURN LOSS (dB) -10 14V -20 S11 S22 -30 FREQUENCY (GHz) FREQUENCY (GHz) Insertion Loss vs. Control Voltage [1] 0 Return Loss vs. Control Voltage [1] 0 0V INSERTION LOSS (dB) 7V 7V 0V 14V RETURN LOSS (dB) -3 -10 14V -20 -6 -9 -30 S11 S22 -12 0 1 2 3 4 5 6 7 8 9 10 -40 0 1 2 3 4 5 6 7 8 9 10 FREQUENCY (GHz) FREQUENCY (GHz) Insertion Loss vs. Temperature, Vfctl @ 7V [1] 0 Return Loss vs. Temperature, Vfctl @ 7V [1] 0 +25C +85C -40C INSERTION LOSS (dB) RETURN LOSS (dB) -3 -10 S11 -6 -20 -9 +25C +85C -40C -30 S22 -12 0 1 2 3 4 5 6 7 8 -40 0 1 2 3 4 5 6 7 8 FREQUENCY (GHz) FREQUENCY (GHz) [1] Low frequency performance limited by external DC blocking capacitors at RF input and output.
