Maxim has introduced a family of femtocell transceivers that can operate WCDMA (bands 1 to 6 and 8 to 10) or CDMA2000 (band class 0, 1 and 10). The MAX2550 family is intended to reduce the number of external components, lower operation and maintenance costs and reduce the size of radio designs for modules and standalone femtocell applications.
A MAX-PHY digital interface is included to eliminate the additional cost and board area used by including an external data converter. All parts have a 4-wire interface. The device features excellent receive blocker performance and what Maxim says is the industry’s lowest noise figure for higher data rates and range. Low-power operational modes are available to minimise power consumption.
So far, Maxim has released specifications for the MAX2551 and MAX2553. The MAX2551 complies to the 3GPP TS25.104 femtocell standard for Band II and V, while the MAX2553 complies to the 3GPP2 C.S0010-D femtocell standard for Band Class 0, 1, and 10.
The transceivers are rated over the -40°C to +85°C temperature range and come in a 7 x 7 TQFN package.
