K-MC1_LP RADAR TRANSCEIVER Datasheet Features LOW CURRENT 24 GHz short range transceiver 8mA @ 3.3V at same performance as K-MC1 3.3V ... 5V supply Less than 30mW power consumption High sensitivity, with integrated RF/IF amplifier Dual 30 patch antenna Buffered I/Q IF outputs Beam aperture 25°/12° Slim 6mm thickness construction Applications Battery operated equipment Traffic supervision Object speed measurement systems Industrial sensors Description K-MC1_LP is a low current, doppler module with an asymmetrical narrow beam for long distance sensors. It is ideally suited for traffic applicatons. This module includes a RF low noise amplifier and two 47dB IF pre-amplifiers for both I and Q channels. The need for external analogue electronics will be significantly reduced by this feature. K-MC1_LP needs 10 times less current than our standard K-MC1 sensor and works from 3.3V or 5V power supplies. An extremely slim construction with only 6mm depth gives you maximum flexibility in your equipment design. Powerful starter kits with signal conditioning and visualization are available.

Calculation: RF-Exposure for 24 GHz transmitter Type identification: K-MC1_LP In accordance to theCFR Part 47, §1.1310and RSS-102 Issue 5 S: Limit for power density according to - CFR Part 47, §1.1310:10 W/m 2 - RSS-102 Issue 5, Table 4: 10 W/m 2 Because the EUT has no antenna connector, which presents the power delivered to the antenna, the measured peak value of the field strength (refer test report F181708E1 of PHOENIX TESTLAB GmbH) was used to calculate the peak radiated power. According to ANSI C63.10-2013 this field strength value was converted to a radiated peak power with the following formula: Calculated peak radiated output power [W] = (field strength [V/m] * measuring distance [m]) 2 / 30 The peak value of the field strength was measured with 107.4 dBμV/m, which is equal to 0.234 V/m Calculated peak radiated output power = 16.4 mW = (0.234 V/m * 3 m) 2 / 30 P:16.4 mW (peak value, refer calculation above) G: 0 dBi = 1 (power is measured radiated, including antenna gain) D: Duty cycle: 100 % = 1 R: Distance in what the limit of S has to be reached: 0.2 m (refer also to the manufacturers installation / user manual) ܵ= ܲ∗ܩ∗ܦ 4∗ߨ∗ܴ ଶ →ܵ= 0.0164ܹ∗1∗1 4∗ߨ∗(0.2݉) ଶ = 0.033 ܹ ݉ ଶ The value of the power density is below the limit of CFR Part 47, §1.1310 for the “General population / Uncontrolled Exposure” and below the limit of RSS-102 Issue 5, Table 4 “General Public (uncontrolled environment)”.
