WJ Communications announced the expansion of its MMIC mixer line with two low-cost high linearity models. These passive gallium arsenide (GaAs) IC mixers are ideally suited for 3G UMTS wireless infrastructure equipment. The MH101 and MH102 mixers offer high dynamic range with Input IP3 greater than 30 dBm and Input P1 dB of 16 dBm across the entire UMTS frequency range of 1.9 to 2.2 GHz.
High IP3 and a low cost package offer linearity in a single chip solution. Housed in standard surface-mount SOIC-8 plastic packages, the MH101 and MH102 do not require any external baluns, bias, matching or decoupling elements. The on-chip diplexer affords first-rate matching on the RF and IF ports and offers excellent VSWR and L-I isolation.
