Frequently Asked Questions
Q1: What frequency band does BLC10G20LS-240PWT support?
A: The operating frequency range is 1805 MHz ~ 1995 MHz, designed for DCS / 3G cellular communication base station amplifier.
Q2: What is the difference between different suffix variants of this series?
A: BLC10G20LS-240PWT uses SOT1275-3 earless flange package. Different tail suffix mainly distinguish packaging form, tape & reel / tray packing, industrial screening grade. Electrical core parameters keep consistent, but cannot directly drop-in replacement if package outline differs.
Q3: Can BLC10G20LS-240PWT be replaced with similar LDMOS transistors from other brands?
A: Partial equivalent alternatives are available, but full verification is required. Different brands have discrepancy on internal matching, memory effect and linearity. Do not directly substitute without re-tuning matching circuit and linearity test.
Q4: What is the maximum junction temperature of this transistor?
A: The maximum allowable junction temperature Tj is 150°C. Good heat sink design must be adopted to prevent overheating damage under continuous operation.
Q5: Is this device resistant to antenna load mismatch?
A: Yes, it can withstand VSWR 10:1 full-phase load mismatch under input power 120W condition, greatly improve field equipment stability.
Q6: What is the pin assignment for SOT1275-3 package?
A: Pin1: Drain1, Pin2: Drain2, Pin3: Gate1, Pin4: Gate2, Pin5: Video Decoupling, Pin6: Video Decoupling (Source connected flange). Reasonable video decoupling circuit helps reduce memory effect.
Q7: What is the typical average output power of BLC10G20LS-240PWT?
A: Under dual-carrier W-CDMA signal test, average output power reaches 60W, typical gain 19.3dB, suitable for medium power base station transmit chain.
