The AP97 series K-band miniature sensor is a Doppler transceiver with a HEMT oscillator, two sin-

gle balanced mixers and bi-static microstrip patch antenna arrays. It is suitable for applications

in automatic access, security, lighting control and speed measurement. It also has I-Q outputs

to discriminate motion direction.

Its lightweight, miniature size and slim profile offer the flexibility to OEMs in making trendy and

slim products.

MSAN-00X AP97 K-Band Miniature Doppler Transceiver Module Application Note V1.00 7. Placing the module in enclosure When AP97 sensor module is housed in an enclosure, it is important to ensure that the performance of the module is not significantly degraded by the presence of the enclosure. A suitable material with both lower dielectric constant and lower loss tangent (that is ABS) is preferred.
