Circuit Description The 24MHZ crystal oscillator drives the base of Y1. The modulation provided by AC6969(U1). The output of AC6969 module (U1)has the matching network consisting that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source The antenna consists of a 2.4GHz PCBantenna There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 3.7 Volt primary battery Feature: Frequency Range: 2402MHz-2480MHz Modulation Type: GFSK, π /4-DQPSK, 8DPSK Antenna Type: PCBA ntenna Crystal: 24MHz
