MAC97A8

MAC97A8 is a bipolar junction transistor (BJT) used as a general‑purpose switch or amplifier in electronics. It typically comes in common packages (TO‑92 and various SMD types), with pinouts that vary by vendor. Exact electrical specs are vendor‑specific, but you’ll generally see Vce in tens of volts and Ic around sub‑amp to about 1 A, with a wide current gain (hFE) that depends on Ic. Uses include small‑signal amplification and switching in consumer electronics. To use it, pick a device with adequate Vce and Ic for your load, bias it in a common‑emitter configuration (with an appropriate base resistor), and provide adequate heat sinking if operating near limits. For precise values and pinout, consult the specific MAC97A8 datasheet from the chosen manufacturer.

Here are the common features of the MAC97A8 RF receiver module:
- 433.92 MHz RF receiver (cheap, widely used)
- Demodulates OOK/ASK signals
- TTL/CMOS-compatible data output (DATA pin)
- Sensitivity around -105 dBm (typical)
- Data rate: a few kilobits per second
- Supply voltage: roughly 3.3–5 V (often used at 5 V)
- Small module size; requires an external antenna
- Low cost; easy to integrate with microcontrollers
- Pinout typically includes Vcc, Gnd, Data, and an antenna connection (variant-dependent)
Note: exact pin names and voltage ranges can vary slightly by vendor module revision.

- Manufacturer: MACOM Technology Solutions (MACOM).
- What kind of company: A global US-based semiconductor company that designs and manufactures high-frequency RF/microwave and millimeter-wave devices, modules, and subsystems for communications, data centers, aerospace/defense, and industrial markets.

MAC97A8 is an 8-pin package, typically the SOIC-8 (small‑outline) package. Some variants may also be available in DIP-8 depending on the supplier.
