InGAP HBT Power Amps
WJ announces the AH212, growing its portfolio of InGaP HBT intermediate power amplifiers. The AH212 is a high dynamic range, 1 W, two-stage drive amplifier, housed in an SMT RoHS-compliant SOIC-8 package. The InGaP/GaAs HBT is able to achieve good performance for various narrowband-tuned application circuits, featuring 25 dB gain, +46 dBm OIP3 and +30 dBm of compressed 1-dB power. This device operates over the 1800 to 2200 MHz frequency band and provides desirable in-band gain flatness. The high linearity performance of the AH212 provides goodl ACPR/ACLR (adjacent channel power/level) performance for spread spectrum applications such as CDMA and W-CDMA. It is capable of providing +23.5 dBm power output for an IS-95A signal at 45 dBc ACPR when operating at 1960 MHz. For W-CDMA the power output is +21 dBm with 45 dBc ACLR when operating at 2140 MHz. The AH212 also has an output return loss of 11 dB at 1960 MHz and 9 dB at 2140 MHz.
