TX_LO_Driver_
VCC1
Transmit LO Driver Positive Power Supply.
40
LO_IN+
Local Oscillator Positive Input, internally AC coupled, internally matched to 50
when the LO is driven single ended
and the LO_IN- is grounded.
41
LO_IN-
Local Oscillator Negative Input, internally AC coupled, differential or single ended capability, ground externally for single
ended operation.
43
LO_VCC1
LO Buffer Positive Power Supply.
45
RX_LO_DRIVER
_VCC1
Receiver LO Driver Positive Power Supply.
47
TX_MX_IN-
Transmit Mixer Negative Input, internally DC coupled, high impedance input. Designed to share a common IF matching
network/IF SAW filter with the receive mixer. Care should be exercised regarding the PC board layout to avoid
interference and noise pickup. Layout symmetry and management of PC board parasitics is also critical for maximizing
the bandwidth of the IF matching network.
48
RX_MX_OUT-
Receive Mixer Negative Output, open collector, high impedance output. Designed to share a common IF matching
network/IF SAW filter with the transmit mixer. Care should be exercised regarding the PC board layout to avoid
interference and noise pickup. Layout symmetry and management of PC board parasitics is also critical for maximizing
the bandwidth of the IF matching network.
49
RX_MX_OUT+
Receive Mixer Positive Output, open collector, high impedance output. Designed to share a common IF matching
network/IF SAW filter with the transmit mixer. Care should be exercised regarding the PC board layout to avoid
interference and noise pickup. Layout symmetry and management of PC board parasitics is also critical for maximizing
the bandwidth of the IF matching network.
50
TX_MX_IN+
Transmit Mixer Positive Input, internally DC coupled, high impedance input. Designed to share a common IF matching
network/IF SAW filter with the receive mixer. Care should be exercised regarding the PC board layout to avoid
interference and noise pickup. Layout symmetry and management of PC board parasitics is also critical for maximizing
the bandwidth of the IF matching network.
52
RX_MX_IN
Receive Mixer RF Input, internally DC coupled and requires external AC coupling as well as RF matching. The
recommend network consists of a 3.3pF series capacitor followed by a small series inductance of 1.4nH and then a
1.2nH shunt inductor. The series inductance is best implemented on the PC board using a narrow transmission line
inductor.
54
PRE_VCC1
PLL Prescaler Positive Power Supply.
56
ITAT_RES1
Connection to external resistor sets the receive and transmit mixers tail currents, independent of Absolute Temperature.
57
PTAT_RES
Connection to external resistor sets the receive and transmit mixers tail currents, proportional to Absolute Temperature.
58
BIAS2_VCC1
Bias Positive Power Supply for the receive and transmit mixers.
59
ITAT_RES2
Connection to external resistor sets the LNA and Preamplifier bias currents, independent of Absolute Temperature.
61
RF_OUT
Low Noise Amplifier RF Output, internally AC coupled and internally matched to 50
.
63
COL_OUT
LNA Collector Output, requires a bypass capacitance which is resonant with the PC board parasitics. A small resistance
(20
)
in series with the main PC board VCC buss is recommended to provide isolation from other VCC bypass
capacitors. This ensures the image rejection performance of the LNA is maintained.
