PMB2208

The PMB2208 contains a direct quadrature modulator and an up/down-conversion mixer with corresponding bias circuitry.

Features of the PMB2208 are:(1)direct quadarature modulator and up/down-conversion mixer on one chip;(2)I/O input frequency range from 200MHz to 550MHz corresponds to an output frequency range from 100MHz to 275MHz;(3)generation of orthogonal carries without external elements and without trimming;(4)typ.48dB carrier suppression with 1VPP baseband level;(5)typ.49dB SSB suppression with 1VPP baseband level;(6)typ.51dB rejection of third-order intermodulation products with 1VPP baseband level;(7)low output noise floor;(8)double-balanced gilbert cell;(9)low noise;(10)power-down mode.

The absolute maximum ratings of the PMB2208 can be summarized as:(1)input voltage:-0.5V to (VCC+0.5)V (VCC4.5V), 5.0V(VCC>5V);(2)input current:10mA;(3)differential input voltage:-2V to 2V;(4)supply voltage:-0.5V to 5.0V;(5)output voltage TREF:-0.5V to (VCC+0.5)V (VCC4.5V), 5.0V(VCC>5V);(6)output voltage MO,MOX:-0.5V to (VCC+1.0)V (VCC4.5V), 5.5V(VCC>5V);(7)output voltage E,EX:-0.5V to (VCC+1.0)V (VCC4.5V), 5.5V(VCC>5V);(8)junction temperature:125;(9)storage temperature:-55 to 125;(10)thermal resistance:140K/W;(11)ESD integrity:-1000V to 1000V.
