PGA460: Short Range Detection

Sadanori Kato

Part Number: PGA460

Hi,

Could you please provide the reference schematic to enable the short range detection(~ 5cm) using the closed-top transducer Murata "MA300D1-1" ?

Best regards,

Hi Kato,

The "PGA460 Mono-static Transducer Transformer Driver Small Form Factor Design File" ( www.ti.com/.../slac754 ) can be re-purposed for use with a high-frequency transducer. You will need to make the following component modifications:
• replace the transducer (J2) with the Murata MA300D1-1
• replace the transformer (T1) with the TDK B78416A2386A003 or Wurth 750316928
• do not populate components C2 and R3 (transducer's tuning capacitor and damping resistor respectively)
