Product Summary
The PMB2208RV1.2 is a direct quadrature modulator and an up/down-conversion mixer with corresponding bias circuitry. The PMB2208RV1.2 splits the signal at the LO/LOX input into two orthogonal carriers. The frequency of the PMB2208RV1.2 is half of the LO/LOX input frequency. The carriers are multiplied with the baseband modulation signals at the A/AX and B/BX inputs. Applications are (1)Vector-modulated digital mobile cellular systems, such as GSM, PDC-800, PDC-1.5, PHS, DAMPS, DCS1800, WLAN, etc.; (2)Various modulatioschemes, such as PM, PSK, FSK, QAM, QPSK, GMSK, etc.; (3)Analog systems with FM and AM modulation; (4)Space- and power-saving optimizations of existing discrete transmitter circuits.
