FAQ:

1. What exactly is the Mini‑Circuits SXHP‑2+? Is it a high‑pass or a band‑pass filter?
   The SXHP‑2+ is a miniature LTCC high‑pass filter, not a band‑pass filter. Its typical 3 dB cut‑off frequency is 2 MHz. The passband extends from 2 MHz to 6000 MHz, making it suitable for applications that need to pass a very wide range of RF frequencies while strongly attenuating signals below 2 MHz. The “201 MHz center frequency” sometimes mentioned in product titles is incorrect and likely refers to a different series such as the SXBP band‑pass filters.

2. What is the typical insertion loss of the SXHP‑2+ and what does it mean for my signal chain?
   The typical insertion loss in the passband is 1.5 dB. This means approximately 70 % of the input power reaches the output. Combined with a typical return loss of 14 dB (VSWR 1.5:1), the filter provides a good match to 50 Ω systems with minimal reflection, preserving signal integrity from 2 MHz up to 6 GHz.

3. How much rejection does the SXHP‑2+ offer below the 2 MHz cut‑off?
   Rejection increases rapidly at lower frequencies. Typical stopband attenuation reaches 20 dB at 1 MHz and exceeds 40 dB below 500 kHz. This effectively removes AM broadcast interference, low‑frequency hum, switching noise, and DC offsets from sensitive RF inputs.

4. What is the maximum RF input power the SXHP‑2+ can handle?
   The filter is rated for a maximum RF input power of 10 W (+40 dBm) at 25 °C. This allows it to be used in moderate‑power transmitter filtering as well as receiver front‑ends, provided proper thermal derating is applied at elevated temperatures.

5. What is the package size and what does “SMD‑8” mean?
   The SXHP‑2+ is housed in a compact 3.2 mm × 1.6 mm (1206 style) ceramic body with 8 surface‑mount terminals. The eight pads include four signal connections and four ground pads. This tiny footprint is fully compatible with standard reflow soldering processes and saves valuable board space.

6. Does the SXHP‑2+ require any external matching components?
   No. The filter is internally matched to 50 Ω. Simply place it in a 50 Ω microstrip or coplanar waveguide trace, connect the ground pads to a solid ground plane, and no additional inductors, capacitors, or matching networks are needed.

7. How does the SXHP‑2+ compare to other Mini‑Circuits high‑pass filters like the SHP‑5+ or SCHF‑17+?
   The SXHP‑2+ offers a much lower cut‑off frequency (2 MHz) than the SHP‑5+ (5 MHz) or SCHF‑17+ (17 MHz). It is intended for applications that must reject near‑DC signals while still passing frequencies as low as 2 MHz. If your lowest signal of interest is above 5 MHz or 17 MHz, those other models can provide slightly lower insertion loss or smaller size, but the SXHP‑2+ is unmatched when you need to preserve signals down to 2 MHz.

8. Can the SXHP‑2+ be used in bidirectional RF systems?
   Yes. As a passive, linear, bilateral device, the SXHP‑2+ filters identically in both directions. It can be placed anywhere in a bidirectional signal path, such as between an antenna and a transceiver, without affecting reciprocity.

9. What are the most common applications of the SXHP‑2+ high‑pass filter?
   It is widely used in wideband receivers, software‑defined radios (SDR), spectrum analyser front‑ends, and general‑purpose RF test setups. Its extremely low cut‑off frequency and wide bandwidth make it ideal for removing low‑frequency interference, DC bias, and AM broadcast energy while preserving signals from the VLF band up to 6 GHz.

10. I need a filter with a “201 MHz center frequency” – should I use the SXHP‑2+?
    No. The SXHP‑2+ is a high‑pass filter with a 2 MHz cut‑off; it does not have a center frequency. If you require a filter centered at 201 MHz with a specific bandwidth, you are likely looking for a band‑pass filter such as Mini‑Circuits’ SXBP‑200+ or similar. Always confirm the exact type (high‑pass, low‑pass, band‑pass) before ordering.
