FAQ
Q1: RF SAW Bandpass Filter hnathawh dan hi engtin nge kan finfiah theih ang?
A: 1) Vector Network Analyzer (VNA) hmangin Insertion Loss (eg, center frequency-ah -1.5dB atanga -3dB typ.) teh rawh.
2) Characterize Bandwidth & Selectivity by plotting S21 to determine -1dB and -3dB bandwidths and out-of-band rejection (e.g., >±100MHz offset-ah 25dB a ni).
3) Check Return Loss (S11/S22) to ensure impedance matching (e.g., >15dB) chhungah passband chhungah a tlem berah reflection a awm theih nan.
Q2: RF SAW Filter Integration atana thil awm dan tlangpui leh chinfel dan tur?
A: Issue 1: Beisei loh taka High Insertion Loss emaw Passband Ripple emaw
A chhan: Filter leh a chhehvel PCB trace/component impedance (a tlangpuiin 50Ω) inkara impedance inmil lo.
Fix: Datasheet-a rawtna angin input/output matching network (eg, series emaw shunt inductors/capacitors) chu verify la, siamrem rawh.
Issue 2: Poor Out-of-Band Rejection emaw Signal Leakage emaw
A chhan: A bul hnaia interfering source atanga EMI coupling emaw filter shield-a grounding tling lo emaw.
Fix: Filter-a ground paddles te chu solid RF ground plane-ah solder tha tak a nih leh nih loh enfiah rawh. Shielding can hmang la, filter chu circuit ri nasa tak (eg, power amplifier, clock) atanga isolate rawh.
