NANO-POLE® Tunable Filters

The NANO-POLE® is designed for optimal size, DC consumption, RF power handling, insertion loss, signal purity and linearity.

The NANO-POLE® provides a minimum center frequency step size of 10 MHz typically but can be modified based upon request. The NANO-POLE® requires a +3.0 V supply that typically draws 5 mA when not hopping.

Offering a 2-pole, Q-constant design, MPG’s NANO-POLE® Tunable Filter provides a close approximation to a Butterworth response, to ensure solid all-around performance in a slim package size.

A pin-diode switched binary capacitor array placed in parallel with a high Q inductor or resonator enables the tunable SPI customer interface, for high versatility and performance.

Features & Specifications

  • Filter frequency: HF, UHF, VHF, L band, S band from 225 MHz to 3000 MHZ.
  • Available in bandwidths from 3-12% with insertion loss of 2.5 to 8.33. Filters can be constructed in x to x sections with an available Q range of x GHZ to x GHz , in tunable bandpass or band reject notch designs.
  • Frequency: HF, UHF, VHF, L band, S band from 225 MHz to 3000 MHZ.

With high power in a small package, the NANO-POLE® Tunable Filter offers the following advantages:

  • Easily tunable device via a simple SPI customer interface
  • +30 dBm in-band power handling: for BW3dB filters ≥ 7%. +27 dBm for 5% filters. +23 dBm for 3% filters
  • 10 µs typical tune time
  • Ultra-small package sizing measuring 0.78” x 0.47” x 0.3” (20 mm x 12 mm x 7.62 mm)
  • 15 dBc typical selectivity at ±10%: 5%, 3% filters provide more selectivity; yet have higher insertion loss
