# BCT5007EXT-TR

**BROADCHIP** · Low Noise Amplifiers (LNA) - RF · SOT-363

BCT5007EXT-TR from BROADCHIP, in a SOT-363. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Supply connection. Operating range 2.6 V to 3.6 V (typical 2.8 V), absolute maximum -0.3 V to +4.2 V. Typical quiescent current is 9.2 mA (EN=2.8 V); shutdown current <0.1 uA. |
| 2 | NC | unconnected | Not connected. Datasheet recommends tying to ground (prefer ground). |
| 3 | RFIN | input | RF input pin, 50 ohm nominal source impedance. Absolute maximum input power 20 dBm. Connects to the GSM antenna network via matching components in the typical application. |
| 4 | EN | input | Enable input. EN(high) supports 1.8 V / 2.8 V IO with an internal 150 kohm pull-down resistor. Drive high to enable the LNA; drive low (or leave low via pull-down) to place the part in shutdown (<0.1 uA, RF path high impedance). Absolute maximum -0.3 V to +4.2 V. |
| 5 | GND | power_in | Ground reference for supply and RF signals. |
| 6 | RFOUT | output | RF output, 50 ohm nominal load impedance. Provides typical power gain of 21 dB at 90 MHz to the FM receiver front end. |
