With a transition frequency of 8 GHz and a noise figure of 1 dB to 1.6 dB across the 900 MHz to 1.8 GHz cellular and ISM bands, this part suits receiver front-ends where sensitivity matters — the noise figure directly sets the cascaded system NF, so a 1 dB floor here keeps the LNA from dominating the receive chain budget. Gain spans 10 dB to 15 dB depending on bias and frequency — enough for a single-stage LNA or buffer before the mixer. The 80 mA maximum collector current and 12 V Vceo breakdown mean it handles moderate power levels in driver or oscillator buffer stages without thermal stress in the SOT-23-3 package. ## Gain, noise figure, and bias point selection The 10 dB to 15 dB gain range is specified without a fixed bias condition — the designer dials in the collector current via the emitter resistor to hit the target gain and noise figure simultaneously. At 30 mA and 8 V, the minimum DC current gain (hFE) is 70, which gives enough loop gain for the bias network to stay stable over temperature. Noise figure is 1 dB typical at 900 MHz, rising to 1.6 dB at 1.8 GHz — the increase tracks the device's fT margin. For a 1.8 GHz LNA, the input match should be tuned for minimum NF rather than maximum gain; the 8 GHz fT provides enough headroom that the trade-off is manageable without external degeneration. Maximum power dissipation is 580 mW at the SOT-23-3 junction — this is the thermal ceiling for continuous operation. In a 50-ohm system with 12 V supply, the transistor dissipates roughly Vce × Ic; staying under 300 mW keeps the junction below 150°C with standard FR4 copper land patterns. The BFR193E6327HTSA1 comes in the industry-standard SOT-23-3 package (also designated PG-SOT23 by Infineon). The three-pin layout — base, emitter, collector — matches the common RF transistor footprint used across the BFR/BFP series, so a single PCB land pattern serves multiple gain and noise figure variants. The tape-and-reel or cut-tape packaging options suit prototype builds and production volumes alike. ## Active lifecycle and compliance status ROHS3 compliant, with no restricted substances above the threshold limits. The operating junction temperature range extends to 150°C, covering industrial and telecom ambient conditions with margin. ## Pin-to-pin alternative: BFP193E6327HTSA1 The BFP193E6327HTSA1 is a direct pin-to-pin alternative in the same SOT-23-3 footprint and package option. Its gain range is 12 dB to 18 dB — roughly 2-3 dB higher across the band — while the noise figure and transition frequency are identical. If the design needs more gain margin without a layout change, the BFP193 drops in with no board spin.","metaTitle":"Infineon BFR193E6327HTSA1 RF Transistor, 8GHz, SOT-23-3","metaDescription":"Infineon BFR193E6327HTSA1 NPN RF transistor, 8GHz fT, 10-15dB gain, 1-1.6dB NF, 580mW, SOT-23-3.
