FAQ：RF Device
- Could you tell us a handling method about the SAW Filter device?
- How do the 2 bit control SPDT switch GaAs MMICs operate in case both of the control signal input terminals are at H level or L level, which are not listed in the functional description?
- What materials are RF devices made of?
- Does latch-up occur in GaAs products?
- Are there any precautions in disposing GaAs products?
- Are the RF devices adopted in reference designs of chipset?
- Are GaAs products sensitive to static electricity (ESD)?
- Can your RF devices withstand a 20-kV contact discharge in the immunity testing of the IEC 61000-4-2?
- Is it possible to mount by manual soldering?
- Can you provide the data for simulation?
- Are there any restrictions on the order in which the power supply voltage and the control voltage are turned on?
- Can the control voltage be set higher than the supply voltage?
- Are there any precautions in designing printed circuit boards for RF devices?
- For the RF devices, are there any precautions in using a multilayer board?
- Does the exposed pad have to be connected to the ground pattern for the RF devices?
- Can you provide evaluation board pattern data (PCB layout) for RF devices?
- Are there any precautions in handling FEMs (Front-end modules) for GNSS?
- In automotive GNSS, receiver sensitivity is degraded due to high cable losses in roof antenna applications. To compensate for this degradation, do you have a high-gain low noise amplifier for GNSS?
- Do you have low noise amplifiers (LNAs) for GNSS 1.2GHz band (L5/2/6 band)?
- It looks that some of your LNAs have a bypass mode function. In what case is the function used?
- I could not get the NF measurement value according to the datasheet. Please let us know how to resolve about this.
- Can a DC voltage be applied to the SAW filter terminal of the FEMs (Front-End Module) for GNSS? Are additional DC blocking capacitors required?
- Is it possible to use a DC blocking capacitor with a value not described in the datasheet for the RF terminals?
- Are there any cases where DC blocking capacitors are required for RF switches not needing DC blocking capacitors connected to the RF terminals?
- In the RF switches, what is the best way to handle unused RF terminals?
- Can your RF switches be used at 13.56 MHz which is out of specifications?
- When a power amplifier was mounted on our application board and evaluated, the output power decreased. Do you have any thoughts about what the cause might be?
- Is an isolator for power amplifier protection necessary at the power amplifier’s output?
- Are there any precautions in storing power amplifiers?
- Do your power amplifiers support the MIPI RFFE provided by chipset vendors?
