nRF2401A power_up pin

hi every one i hav brought nRF2401A Transceiver with Chip Antenna (WRL-00152). According to the datasheet of nrf2401a power_up (pin no 23) has to be made high to enter into configurtion or active mode,but the module which i have has power_up pin left open. n since the ic package is punch QFN24 i’m not able to access that pin. so can u tell how to solve this problem… n has any1 work on same module.

Thank You.
