fm transmitter 88 108mhz ic

Posted on Feb 4, 2014

The MAX2605, MAX2609 are compact, high performance intermediate frequency (IF) voltage-controlled oscillator (VCO) designed specifically for demanding portable wireless communication systems. They combine monolithic construction with low noise, low operating power consumption of a small 6-pin SOT23 package. Low-noise VCO, a feature on-chip varacto

r and feedback capacitors that eliminate the need for external adjustment elements, so the ideal MAX2605, MAX2609 for portable systems. Only an external coil is needed to establish the frequency of oscillation. In addition, a buffer integrated differential output is provided for driving a mixer or prescaler. The output buffer is capable of providing up-8dBm (differential) with a simple power game. It also provides isolation from load impedance variations. The MAX2605, MAX2609 operate from a single 2. 7 V to 5. 5 V supply and provides low power consumption. IF these oscillators can cover the frequency range of 45MHz to 650MHz.
