Frequently Asked Questions
Q1: What operating frequency band is supported by FLM5964‑4F?
A: 5.9 GHz‑6.4 GHz, standard C‑band satellite uplink frequency band.
Q2: Does FLM5964‑4F need external 50‑Ohm matching network?
A: No. Internal 50‑Ohm input/output matching, connect directly to 50‑Ohm microstrip lines.
Q3: How to mount FLM5964‑4F for reliable thermal performance?
A: Bolt the metal‑ceramic flange firmly to heat sink with thermal compound. Keep channel temperature ≤ +175°C.
Q4: Can FLM5964‑4F be adopted for new‑product design?
A: Obsolete / NRND. Stock is only for legacy‑equipment repair. Select modern RF power FET for new projects.
Q5: What pin‑compatible alternatives are available in FLM5964 series?
A: FLM5964‑8F, FLM5964‑12F share same IK‑flange package and frequency band with higher output power. Not direct drop‑in replacement, verify P1dB, gain and DC bias before use.
Q6: What does ‑46 dBc IM3 performance stand for?
A: Typical ‑46 dBc third‑order intermodulation @ Po=25.5 dBm, delivers clean signal for multi‑carrier SATCOM uplink.
Q7: What is absolute maximum gate‑source voltage?
A: Operating VGS bias: ‑0.5V ~ ‑3.0V; max rating ‑5V. Do not exceed ‑5V negative gate voltage to avoid permanent device damage.
Q8: Are there other package options for FLM5964 series?
A: No SMD variant available. All series use identical IK hermetic bolt‑down flange package.
Q9: How to get datasheet, S‑parameter and volume quotation?
A: Submit Quick Inquiry form for datasheet, S‑parameter file, stock check and bulk price.
